Galaxy Zoo and the Nobel Prize

No, no one on the Zoo team has won the Nobel Prize. But there are interesting connection with the 2009 Physics prizes, just announced by the Swedish Academy. The prize was shared by Charles Kao, Willard Boyle, and Charles Smith. Kao’s work contributed greatly to making fiber optics feasible for reliable transmission of signals at high bandwidth, a prerequisite for the Internet as we know it today. And incidentally, optical fibers have multiplied the effectiveness of spectrographs for astronomical surveys, by letting us pipe light from hundreds of objects at once into a single spectrograph; this is how all the SDSS spectra examined by Zooites were obtained.

Boyle and Smith shared the prize for their work in inventing charge-coupled devices. These are the electronic chips used for digital images, which have multiplied the reach of astronomical telescopes and worked their way into tens of millions of digital cameras. Compared to photographic emulsion, CCD chips are vastly more sensitive, can be calibrated more accurately, are reusable, and provide their output immediately in digital form for computer analysis or telemetry. Of course, the Sloan Digital Sky Survey made good use of these properties, with a mosaic of CCDs behind five different filters scanning the sky.

Finally, I suspect the prize committee was aware of the Galaxy Zoo project. At the very end of their excellent document on the science behind the prizes, we read:

“In science, the possibility of transferring and processing images digitally is a real revolution. Digital image processing is now a global commodity which enables, for instance, the best international expertise to be involved in crucial diagnostic and even surgical situations, through remote control and feedback through digital cameras. Furthermore the evaluation of large amounts of data (e.g. created in mapping the universe) can be spread to many groups and even to volunteers from the general public.”

Hmmmm. Data mapping the Universe, whose evaluation is shared among volunteers from the general public. That reminds me of something… At any rate, I think I can speak for the whole Zoo community in saying to Kao, Boyle, and Smith – congratulations, and a special vote of thanks!

Galaxy Zoo gets a mention on The Archers

Someone sent me the following link:

Google Powered GZ2 Bar drawing spin off, 1 down….

Spiral Galaxy

Firstly, I’d like to thank all those users who have used the bar drawing website. As of yesterday at 10pm we have recorded responses from 97 unique users and every galaxy had been looked at by at least one user. This is excellent news and we are delighted with the response the site has received.

We have reached a significant milestone, but we still need more help! To do reliable science, much like the main Galaxy Zoo site we want to have multiple users look at each galaxy. So keep drawing!

The site can be found here: http://www.icg.port.ac.uk/~hoyleb/bars/ and the forum here.

We know some users have experienced problems accessing the site. We apologise if this has caused frustration. We remind you that our site is best viewed in Firefox[download here] – response with IE is particularly unreliable. Right now the bar drawing site is hosted at the University of Portsmouth, so the server is not as fast as the main Galaxy Zoo server. If site speed continues to be a problem and/or we start attracting significantly more users we will consider moving the site. Also remember that Google Maps set the zoom level. If you zoom in further than they have data you will see only a white image. Just zoom out until you can see the galaxy. Most other problems can be solved by hitting the reset button  –  if you reload the page you will move to the next galaxy.

Due to popular demand, we have added a counter to the site, showing you how many classifications you have made.

Thanks for all your help and input.

Zooing all over the world

I last updated the Galaxy Zoo city league table back in April. How do things look now? In good old fashioned reverse order :

10 Down from 2nd last time, Manchester. Having e-MERLIN to play with is obviously distracting our good friends at Jodrell.

9 A new entry – Los Angeles. Presumably Hollywood doesn’t have enough stars of its own.

8 Berlin The first non-native English speaking city to make the list. Will it be the highest?

7 A suprise 5th last time, Bristol is down two spots this time.

6 The third new entry in a row is Melbourne, according to Wikipedia home to the world’s largest tram network.

5 Down two spots from 4th last time, New York is the highest ranked American city.

4 The team behind the Polish translation of Galaxy Zoo 2 have been working hard, and they’re rewarded by seeing Warsaw in 4th place. It’s not the highest new entry, though.

3 Rising four places, Sydney. Australians can’t stand the sight of a league table they’re not on the top of.

2 In second, this chart’s highest new entry – Eindhoven. A stunning performance from our Dutch classifiers.

1 But hanging onto first place in the Zoo classification stakes is London. Can anything topple the legions of office-bound zooites from the top of the tree?

She's an Astronomer: Aida Berges

aida


Entrevista de Aida en español


Aida Berges (“lovethetropics“) lives in Puerto Rico with her husband and children. Originally from the Dominican Republic, she studied there in an all girl Catholic school (Colegio del Apostolado) where she was inspired by her her history teacher (Rosa Maria Reyes Feriz). After graduation she started a university degree in Law where Supreme Court Judge Ana Rosa Berges Dreyfuss (a family member) became a beloved teacher. After finishing her degree in English at a different university, she worked various secretarial jobs and as a translator. She moved to Puerto Rico to live with her eldest brother and his wife, and there met husband (Benito Garcia Mendez). Her main job for the last almost 30 years has been as a dedicated wife and mother to children Benny and Laura (now grown; Benny works in retail and Laura is finishing her Masters’s degree in Psychology). The family spent most of this time in Puerto Rico, except for a 7 year spell in New Jersey where the children were born. Aida loves to read history, science fiction and fantasy.  She has 3 dogs and one cat.  And she loves the ocean, especially going to the beach or just watching the waves.

  • How did you first hear about Galaxy Zoo?

I was reading CNN online and found an article describing how a very young teacher from the Netherlands had found a new kind of object and it was called Hanny’s Voorwerp.  It was an article to celebrate the first year of Galaxy Zoo.  I went to Galaxy Zoo immediately and my life changed forever…It was like coming home for me.

  • What has been your main involvement in the Galaxy Zoo project?

I am part of the Irregulars Project and also the Hyper-Velocity Stars Project (and check out their blog).  In the Irregulars Project I look for irregulars galaxies and send them to Richard Proctor to be integrated into the hunt.  We now have more than 17,000 irregulars and the numbers keep growing every day. And we still need the help of the Zooites with their clicks on the Irregular Hunt (check out the Irregulars Project forum discussion).   I send Richard between 100 and 500 possible irregulars every week. I also worked on the three Pea hunts, the Mergers hunt, the Voorwerpjes hunt and the Supernova hunt. And I found an unusual green object ages ago which has been dubbed Aida’s disturbed green mystery object and has been an object of the day (OOTD). We still don’t know what it is.

Both major projects I’m involved have been pure coincidence or serendipity.  With the Irregulars Project I was the one getting the galaxies for the hunt and when we decided to write the first paper about astronomy without being astronomers I was included.  I classified by myself 24,000 galaxies to clean the sample from spirals, elliptical galaxies, artifacts and unidentifiable blobs.  Then classified 12,000 more!

For the HVSs project it was pure coincidence that I found two in about five minutes.  I had to Google the term Hyper-velocity Stars because I had no idea they existed.  Posted it on the newbies thread and I had to post an “Object of the Day” (OOTD on High Velocity Stars) and Thomas Jennings gave me the idea to post the known HVSs. Zookeeper Jordan read the OOTD and got so excited a group of fearless zooites decided to look for more, I am one of them…we are almost ready to post the first entry on a new thread for them on Galaxy Zoo. So far there are only 16 or 17 known HVSs.  But we are still very optimist we can find more of them even if it is for sheer numbers. (We zooites are bigger than the Swiss Army.)

  • What do you like most about being involved in Galaxy Zoo?
What I like the most is helping scientists discover new things and being there when that happens. And the people at the Zoo are wonderful, starting with the Moderators, Zookeepers and Zooites.  For me it feels like coming home.
  • What do you think is the most interesting astronomical question Galaxy Zoo will help to solve?
With every question we answer we get ten new questions. First I would like to know the place of the Irregular Galaxies in the universe. Then would like to know if there are other Voorwerpen and would like to know how the Voorwerpje saga ends. And how the spiderweb ring galaxies (Eds note: Aida’s name for ring galaxies with very low surface brightness extended rings like this one) are formed. They are the most beautiful galaxies for me. And how the shockwave ring galaxies are formed too. So many questions, so little coffee.

  • How/when did you first get interested in Astronomy?
When I was young I lived in the country so the moon and stars were spectacular…ever since I first saw the stars I have been interested.  I started to surf the internet because I wanted to read everything I could about astronomy.
  • What (if any) do you think are the main barriers to women’s involvement in Astronomy?
Well, I come from a third world country, the Dominican Republic.  In my time girls were supposed to marry young and be housewives, but now I see that the universities there are full of women studying and that makes me so proud. There are no barriers now for us, maybe just a few reluctant men, but we are winning.

  • Do you have any particular role models in Astronomy?

I would have to say that the Zookeepers are my role models because before getting involved on Galaxy Zoo I didn’t know any astronomers. Chris Lintott and Jordan Raddick specially because we are doing the Irregulars Project together. And Jordan Raddick is double because he is helping us with the HVSs. And Bill Keel (NGC3314), I am helping him get more possible Voorwepjes. Thomas Jennings started the Newbies thread and has gone back to college to study Astronomy.  That’s what I call commitment. The person who inspired me to love science in general was my sister Adolfina.  She is a medical doctor with specialties in Pediatrics and Hematology.  She and her husband, who is also a hematologist discovered an element in the blood unknown until they found it.  She is also the best and most loving sister anyone can have.

I would also like to include thanks to my parents Rafael Bergés Lara and Thelma García de Bergés, and my Uncle Manuel Bergés Lara and Aunt Carmen

Google-powered Bar-drawing Zoo2 offshoot

Hello Zooites.

Once again we need your help with more detailed classifications of a
selection of galaxies.

We’ve made a sample of interesting galaxies from Galaxy Zoo2, most of
which have bar structures, and we would like you to measure the length
and thickness of the bars. Also we’d like you to check the shape of
the galaxy and tell us how the spiral arms and bars are linked.

We are also pioneering the use of the Google Maps interface for Galaxy
Zoo science, which allows us to perform tasks like drawing on
galaxies. Please note, that the bar drawing pages work best with
Mozilla Firefox.

Head over to our site: http://www.icg.port.ac.uk/~hoyleb/bars/ and
log in, using your Galaxy Zoo user name and password, to start
classifying.

We’ve describe the our science
rationale: htp://www.icg.port.ac.uk/~hoyleb/bars/tutorial.php#s1 and there is a forum topic related to this page: http://www.galaxyzooforum.org/index.php?topic=276269.0

See you on the bar site!

Bye,

Ben and Karen [on behalf of the bar drawing team].

Galaxy Zoo motivation study paper accepted!

Our paper on the motivations of Galaxy Zoo users has been accepted for publication in the journal Astronomy Education Review! Now that the paper has been accepted, I have posted it on the arXiv system. Head on over and read it if you’re interested in hearing more about the interviews we did with some of you to learn what makes Galaxy Zoo appeal to you. I wrote a summary of the paper for this blog a while back, but now you can read the paper itself.

The paper should appear in the Galaxy Zoo Library in the forum soon, and Pamela, Georgia, or I would be glad to answer any questions you have about the paper there. The next step in this research is to analyze the data from the survey that many of you took, and we’re working on that step now. Updates on that will come soon. Thanks to my lovely co-authors, and of course to all of you, without whom this none of this research would be possible!

She's an Astronomer: Kate Land

land300

Dr. Kate Land is from sunny Sussex on the south coast of the UK and her research/studies have taken her to Cambridge (undergrad), Imperial (PhD), and then Oxford (postdoc). Her PhD was on the Cosmic Microwave Background radiation, and in particular exploring anomalies in the WMAP data and their implications for our cosmological models. During her postdoc, her research continued to focus on cosmological observations, such as galaxy surveys and supernovae data, and what they might tell us beyond our current understanding. While a postdoc in the Astrophysics group of Oxford University, Kate had the pleasure of sharing an office with Dr. Chris Lintott. But she assures him that this had nothing to do with her decision to leave the field and enter into a new profession! Kate now works as a quantitative researcher in finance, and enjoys living in London with her boyfriend and savoring the delights of North London pubs at the weekends.

  • How did you first hear about Galaxy Zoo?

In the pub with Chris! Another cosmologist (Anze Slosar) and myself were interested in investigating recent claims in the literature about the rotations of spiral galaxies in our local universe aligning in an unlikely way (they shouldn’t really align at all!). But we realised that we’d have to go through thousands of images of galaxies (or develop some software) to identify the handedness of the galaxies. We thought about dumping a laptop in the coffee area of our department to get people to help, and I asked Chris for advice over a pint one evening – because I knew he was very good at crowd-sourcing (having already got children from around the world to observe a quasar for him 24 hours a day!). He then told me about Galaxy Zoo, which was in its infant stage at this point. And it was a great match – our project would fit in perfectly, adding another scientific motivation to GZ while Anze and I would provide some more ‘man’ power!

  • What has been your main involvement in the Galaxy Zoo project?

I was pretty heavily involved in all stages of the project for its fist year from helping to test the site, monitor traffic, analyse data, interact with zooites, deal with the press, and eventually publish papers! I was part of the front line when it all kicked off in July 07 – and I mean front line! It was madness with thousands of emails a day coming in, media people ringing for interviews, and servers exploding! I loved answering peoples questions but we quickly realised that we couldn’t keep up with the emails and we launched first the FAQ page on the site, and then the forum. The media part was fun too… doing live radio interviews on the fly, and helping with pieces for New Scientist, Physics World, etc. About 9 months after Galaxy Zoo launched we submitted the first Galaxy Zoo paper. It was an awesome moment for me, and the whole project, when it got published.

  • What did you like most about being involved in Galaxy Zoo?

The popularity of the site was absolutely heart-warming. I used to get quite emotional reading emails and posts on the forum from zooites who loved the project and were wild about astronomy. So much of an academic’s work can be remote, abstract, and cut off from the ‘real-world’. And it was just brilliant to work on something that touched so many people.

  • What do you think is the most interesting astronomical question Galaxy Zoo will help to solve?

The cosmology ones! But I am biased… to be totally honest I didn’t know much about galaxies when I first got involved with GZ. I was, and remain, more interested in cosmology; the study of Universe as a whole. And as objects sitting in space, galaxies can reveal a lot about how the Universe is expanding, and any invisible forces that are influencing them.

  • How/when did you first get interested in Astronomy?

As a kid I was always fascinated by big questions, like ‘where is the edge of the Universe?’, and ‘what is empty space made of?’. I couldn’t sleep sometimes for getting myself so confused and freaked out! My granddad was also a massive influence on me – he was a mathematician, and fascinated by astronomy. At 7 he bought me a calculator, at 8 a star chart, and at 9 a subscription to the Junior Astronomical Society. I also got handed down a telescope about this time and saw some of Jupiter’s moons and Saturn’s rings from my bedroom window. Very cool! Maths became my thing at school, college, and Uni. But in my second year at Uni I got back into astronomy – heavily influenced by images from the Hubble telescope which are gorgeous and awe inspiring. I found the scales, temperatures, and physics involved with the stuff going on in the Universe very exciting – and I was chuffed to be able to do the final year of my degree in Astrophysics (rather than Maths). This was the first step towards me becoming a theoretical cosmologist, and thinking about those big questions again!

  • What (if any) do you think are the main barriers to women’s involvement in Astronomy?

I don’t know of anything stopping women getting involved in amateur astronomy. But I don’t think the academic career path suits women particularly well. I was always given enormous encouragement from my peers and never felt discriminated against. But I personally wasn’t keen on the post-doc circuit of moving about every few years… I wanted to plan for the future and ‘nest build’ somewhat, and in a location of my choice! I think this is more of a female thing – to agonise over the future. But it might have just been me being unadventurous!

  • Do you have any particular role models in Astronomy?

My supervisor, Prof. Joao Magueijo, was an enormous influence on me. Not only a genius, but a lot of fun to work with – very supportive, unpatronising, and encouraging with his students and very involved in the research we did together. Another inspiration is Dr. Sarah Bridle, of UCL. A very smart woman, who is refreshingly unpretentious and friendly! I’d say she is a great role model for female academics.

Voorwerping, Part 1

I’m working on the Suzaku data that we’ve obtained on IC2497, the galaxy next to Hanny’s Voorwerp. X-rays, especially the really energetic ones that Suzaku is able to detect are probably the best way to probe whether the black hole in a galaxy is actively feeding or not. Shanil Virani and I are currently working on the data reduction and analysis, which is quite challenging. Early indications are that the data will show us some really exciting things, but the problem is that they make us really scratch our heads. It may yet take us quite a while to see if we understand what’s going on and we may have to pick the brains of a theorist or two. So, stay tuned….
