Next GZ Hangout: Wednesday, 10th April, 19:00 GMT

We’re trying a new time for our hangouts to make it easier for those of our viewers in North America to tune in live. Our next live hangout will be on Wednesday the 10th of April at 7 pm GMT. That’s 9 pm in Europe, 8 pm in the UK, 3 pm EDT and 12 pm PDT. Even if you live in Hawaii you won’t have to skip your morning cuppa to hang out with us (9 am HST)!

Update: The video link and the summary post (also with a video link) are here.

If you have any questions you’d like the science team to answer live on the air, please feel free to leave a comment below, or tweet them directly @galaxyzoo. During the hangout, if we use a term you’re not familiar with, you can use the jargon gong by tweeting at us too. For example, “@galaxyzoo GONG laser guide star” would have been perfectly appropriate during the last hangout. Go on… gong us! We like it!

    This may be a rather off the beaten track (set of) question(s) …

    In preparing a document for submission to a journal, for publication as a paper, how do you decide who should be the paper’s authors? The lead author?

    How do you decide which journal to submit it to? Can you submit the draft to more than one journal?

    Does the lead author have the responsibility of getting every other author’s OK, on any changes (e.g. after getting a reviewer’s comments)? Who does the proof-reading?

    How do you expect the UK’s new Open Access policy to affect papers by Galaxy Zoo Science Team authors (on GZ topics)?

  2. Jean Tate says :

    A question on dust: once created, how is dust destroyed?

    I’m particularly interested because in this recent preprint Calcium H & K Induced by Galaxy Halos the authors report discovery of CaII waaaay out into the IGM (and apparently there’s been a paper on a similar discovery for MgII); if metals from AGB stars and SNe can get out, so can dust, surely (not to mention the dust that would escape in a merger, in the tidal tails).

    Yet in this other recent preprint, Coevolution of dust, gas, and stars in galaxies – I. Spatial distributions and scaling-relations of dust and molecular hydrogen, the section on dust destruction (2.2.3) seems to imply it’s supernova blast waves that destroys dust, and only close to such SNe.

    And what about people in South africa? #Feeling_so _left_out

  4. Dhritisundar Datta says :

    Would like to know if the recording would be available later.

    • Brooke Simmons says :

      Yes, definitely — after the hangout has finished I’ll write another blog post summarizing it, and the video will be viewable from there or directly on YouTube. We’ll also make the audio available as a podcast. Thanks for tuning in, live or not! 🙂

      • Jean Tate says :

        As YouTube is unavailable in China, is there a way zooites in China can access the hangout? Given the, um, late hour in China (and also in the rest of the Far East, including Australia), I doubt that any zooite from that part of the world will be tuning in for the live broadcast (well, I guess some Kiwi zooites might).

  5. John Webb says :

    It might help to explain what your ‘live hangout’ is and what can be gained from it! – I have no idea what you are talking about.

    • Brooke Simmons says :

      Hi John,

      Sure — they’re just informal chats where the science team all connects via video chat and “hangs out” to talk about astronomy (most of the time) and answer questions. We don’t rehearse or have a script but we do take questions beforehand via the blog, Twitter, Facebook, Google+ etc. You can watch live and continue interacting live via Twitter and the blog, and you can also watch the hangouts later as recorded videos or listen to them as podcasts. It’s meant to be an enjoyable way to learn a little bit about whatever astronomical topic you or others are interested in. Sometimes we talk about Galaxy Zoo specifically, but other times it’s more general. Anything goes!

      Here’s a post describing how we started doing these:

  6. Brooke Simmons says :

    Hi Jean,

    It’s essentially impossible to pick a time that works for everyone, so we’re planning to rotate through different times while still finding a time that works for the science team’s diverse schedules. I suspect we will be able to record at a better time for Australia, China etc. sometime in the future — perhaps while we’re at the next Galaxy Zoo conference down under.

    In the meantime, though, YouTube is not our choice — it’s built in to the hangout system, so that’s Google’s decision. I’m afraid the porosity (or lack thereof) of the Great Firewall is slightly outside the scope of the hangouts…

    • Jean Tate says :

      Thanks Brooke, I did not know that (about you having no choice about YouTube).

      Maybe how to allow zooites in China to view GZ Hangout videos could be discussed at the next dotAstronomy unconference? Or the Zooniverse developer community could be polled for suggestions? Clearly beyond the GZ Science Team’s remit!

  7. Tralf says :

    I’ve been doing Galaxy Zoo for a only a short time, but it’s a wonderful thing to be using those elective credit classes for more than playing Jeopardy.

    Question: the website boasts of an app available on iTunes, but it doesn’t exist on the Canadian iTunes. And although I can see it there on the American and UK store, I cannot download it. I’m sure there are others around that may like it too. Can anyone please fix that? Or know a way to work around it?

  8. Jean Tate says :

    It would seem – from c_cld’s excellent post in the “Uncanny Valley” Spiral Galaxies? thread (and an old post, by NGC3314, which I can’t find just now 😦 ), that your perceptions of the morphology of a galaxy can be strongly influenced by the choice of band/filters used to make the RGB JPEGs GZ zooites are served up to classify (in addition to the usual stretch factors, thresholds, de-pixellation, etc).

    Are there any active plans for a new Zooniverse project (or another iteration of GZ perhaps) to explore these effects? E.g. prominence – even visibility – of features such as star-forming regions, arms, rings, bars, and bulges, as a function of bands used?

    I’m particularly interested because it seems – based on very little actual evidence though – that low-z (say ~2) galaxy may be missed because the only bits visible in the IJH images are the disconnected, blobby/clumpy star-forming regions (and the bulge/nucleus entirely missing).

    • Jean Tate says :

      Oops! Somehow a whole line (more?) of my previous comment got killed! Why? because the WP interpreter – stupid, dumb thing! – took my “less than” and “greater than” symbols (you know, above the comma and period on your keyboard) as part of an HTML tag!!!

      The last para *should* read something like, with “lt” meaning “less than” (etc):
      “I’m particularly interested because it seems – based on very little actual evidence though – that low-z (say ~lt0.3) spirals may look like ellipticals or lenticulars, because the star-forming regions, and even the arms, may be invisible in IJH images. And a high-z (say ~gt2) galaxy may be missed because the only bits visible in the IJH images are the disconnected, blobby/clumpy star-forming regions (and the bulge/nucleus entirely missing).”

  9. John Murrell says :

    I have a question on the Old Weather section. Would it be possible to ask the ‘crew’ looking at the logbooks to flag any items that might be sightings of Noctilucent Clouds. My reasoning is that ships had all night watches and if NLC were visible they might well record them. This is particually important for any logs before 1885 which is the earliest sighting though there is some indication in an earlier report from the Armargh Observatory. The combination of the ships location, date & time should allow a lot of non-NLC reports to be elliminated as they only occour for a few weeks around mid summer and when the sun is 5 to 15 degrees below the horizon.

    • Brooke Simmons says :

      Hi John,

      I think none of us are really as qualified to pontificate on Old Weather as we’d have to be to feel comfortable doing so live on the internet. 🙂 However, I’ll point the OW team to your request!


      • John Murrell says :

        Thanks Brooke,

        I thought the hangout covered the entire zooniverse and therfore thought Chris Lintott might be on to field this one. Grateful if yuo would pass it on to the old weather team as there are no contact details on that section of the zooniverse.

  10. elizabeth says :

    Interesting! Like the new time.

  11. zachary jacobson says :

    I’m trying to get on here.
    Menwhile, the picture bove is one I sent comments in, about.

  12. Arlo James Barnes says :

    There is probably resources for this somewhere, but what is the significance of the number of arms if it seems so subjective?

    • Brooke Simmons says :

      I’m really sorry we didn’t see this question until the hangout was over! I think this may be worth writing a separate blog post about in order to answer it. More soon…

      • heatherwatmore says :

        I am too scared of making a mistake when sorting out the stars that I dare not go into the site and yet I do want to

  13. John Fairweather says :

    Interesting discussions, I look forward to attending further ones at the RAS in May and ZoonCon 2013 in June.

    One point I would say, is some of the displayed galaxies might be better displayed, in showing the inverse colour, ie, black stars against a white background.

    I don’t know if other zooniverse projects do a similar discussion, but it might be of use to have other SMEs (Subject Matter Experts) give a similar presentation.

    PHYSICAL if the middle of the atmosphere and where the light is going to very quickly a certain value that this value is surely differ in outer space to the different middle … What is your opinion in this Please advise .. You can also communicate through (moh_kotb2020 @ yahoo. Com)
