She's an Astronomer: Vardha Nicola Bennert

Dr. Vardha Nicola Bennert is a postdoctoral researcher (“postdoc”) in the Physics and Astronomy Department at the University of California (UC) in Santa Barbara.  Originally from the Ruhr area in Germany, she completed her PhD in 2005 on the astrophysics of active galaxies at the Ruhr-University of Bochum. She then moved to the US for a first postdoc at UC in Riverside, before moving to Santa Barbara in 2008.

Dr. Bennert’s research interests focus on the central region of “active galaxies” (the black hole and the so-called narrow- and broad-line regions immediately around the black hole) and its relation to the host galaxy. She enjoys working in the stimulating research environment at UCSB and living in Santa Barbara – especially because the sun is always shining and the beach is so close! But she also misses her friends and family in Germany. In her free time, she loves to explore the outdoors of southern California, and is also on an inward journey, integrating meditation into her everyday life.

  • How did you first hear about Galaxy Zoo?

By coincidence! I was at UC Riverside and had an upcoming observing run at the 3m Shane telescope at Lick observatory when Prof. Bill Keel contacted my supervisor, Prof. Gabriela Canalizo, asking whether we could get a spectrum of “Hanny’s Voorwerp”. I agreed, went observing, had several clear nights and was able to get the spectrum. I was immediately intrigued by the object as the spectrum looked very familiar to me – very much like the narrow-line regions of active galaxies that I studied intensively during my PhD thesis, except that there was no evidence of an active galactic nucleus in the center!

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

I helped in the reduction, analysis, and interpretation of the  spectroscopic data which were integrated in the discovery paper of the Voorwerp. Later, by another coincidence, the team was looking for someone with experience in reducing HST images, which I have. So I obtained, reduced and analyzed HST images of the “peas” discovered in the Galaxy Zoo project. This formed part of another paper in which I helped in the interpretation of the results.

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

It is great that so many citizen astronomers are involved, and that it has such a strong public outreach component. For me, public outreach is not only our duty as researchers who are basically funded through the tax payers’ money but something that I enjoy a lot. I love seeing how people get excited about astronomy and the research that I am doing.

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

Galaxy Zoo has proved its value in revealing rare and interesting objects like the Voorwerp, through inspection of images by eye, showing the great advantage of  humans over robots! I think this, more than answering a particular question for which Galaxy Zoo was set up, will be the lasting legacy. These rare objects have the potential to provide us with new and surprising insights.

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

As a child, I loved looking at the stars, and was fascinated by the books by Prof. Stephen W. Hawking, although I did not understand much at the time… However, this did not turn me off from pursuing a scientific career. On the contrary, I always found it exciting to be at the edge of my understanding and learn new things all the time.

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

I do not like the very competitive way in which scientific results are promoted. Personally, I think that it must be difficult for women to have children while pursuing an astronomical career, since both tasks are quite time demanding. But of course, there are many women in astronomy who prove that it is possible.

  • Do you have any particular role models in Astronomy?

My PhD advisor, Prof. Hartmut Schulz, had a strong influence on me. I always considered him to be one of those “old-fashioned” professors who not only know so much about astronomy, but who have a profound general education with the emphasis on thinking for one’s own. Prof. Schulz sadly died in August 2003. I remember him gratefully for having been my “Doktorvater” in the truest sense of the word.

Also, my current supervisor at UCSB, Prof. Tommaso Treu, is a constant inspiration – he is not only very smart and extremely effective, but he is also always joyful, full of energy, and helps his students to make the best out of their potential.


This post is part of the ongoing She’s an Astronomer series on the Galaxy Zoo Blog in support of the IYA2009 cornerstone project of the same name (She’s an Astronomer).

This is the second post of the series, last month we interviewed Hanny Van Arkel (Galaxy Zoo volunteer and finder of Hanny’s Voorwerp).

Next in the series: Alice Sheppard (forum moderator).

Merge complete!

We’ve had a busy afternoon here at the Zoo working hard to merge the Galaxy Zoo and Galaxy Zoo forum user accounts.  I’m pleased to say that the process is now complete!

The details of the merge process have been outlined in this earlier post but basically some of you will have had your accounts merged automagically, others of you will have to ‘reclaim’ your old Zoo or forum account by using our merge tool.  If you are having trouble logging in since the merge then please use the password reset form at this address:  https://galaxyzoo.org/signup

Unfortunately as a consequence of moving the forums to a new server some people won’t be able to see the forums for up to 24 hours.  Don’t worry though, they are there and you’ll be able to see them soon!  (It’s a DNS propagation issue for you tech-minded folk out there.)

Merging the different accounts has been a long-term goal for us at Galaxy Zoo and we’re really pleased to finally have the right solution in place.  It’s been a real programming challenge to get the logic just right and it wouldn’t have been possible without a huge amount of effort from Scott Miller and Pamela Gay and the rest of her team at SIUE – thanks guys!

We realise that the merge may cause problems for a few of you so if you have any questions or are having trouble logging in then please email us at team@galaxyzoo.org

Cheers

Forums merge part deux

You may have noticed that the forums are again in maintenance mode and new registrations are disabled on the Zoo at the moment. That’s because we’re currently churning away in the background merging the accounts from both databases. For more information have a read of our earlier post We should have some more news for you later today…

New from the Zoo – gas clouds around active galactic nuclei

With the excitement about new observations of Hanny’s Voorwerp, this might be a good time to point out that Zoo participants are finding new examples of a related (albeit less spectacular) class of objects. (That was evidently my roundabout way of saying “hey, everyone, you can look for these too!”). What do these four galaxies have in common?

If at first you don't succeed…

So it’s been a busy 24 hours at Galaxy Zoo.  As we outlined in the earlier posts were working hard on unifying the Galaxy Zoo and Galaxy Zoo forum accounts. During the merge we had to disable the forums and new registrations on the Zoo so that we could be sure of exactly who was registered where.

So 24 hours later and with some tired eyes I’m sorry to report that we ran into a few technical difficulties with the merge. Specifically, the tests we had in place for checking the post-merge user accounts showed us that we had some problems. It’s of prime importance to us that we get this right and once we’d done the merge we weren’t completely satisfied that things were exactly as they should be.

So what next?

We’ll by now you should see that the forums are back up again as are new registrations on the Zoo and so we’re back to how things have always been. We’re going to review what happened yesterday, figure out what went wrong and then have a go again in the next week or so. Watch this space!

Cheers

Things are moving slooowly

So the long promised forums/Zoo accounts merge is underway but unfortunately things are moving a little slower than we’d like.  The good new is we’re making good progress, the bad news is the forums won’t be back up until tomorrow now – sorry!

More news in the morning…

Cheers

Arfon

You may notice a few new things are going on around the Zoo today. From today, you should be able to log in to both Galaxy Zoo itself and the forum at the same time with a single login and password. We are also creating a single profile page, so you can edit all your details in one place. We should have done this in the first place, but better late than never!

The short version of this post is that the sites will be down for a few hours today, and then you’ll be able to login to both the Zoo and forum with the same login. If you want the gory details, then read on :

Changes are coming…

Today is a big day for those of us who work behind the scenes at Galaxy Zoo.  More news later but for now the forums are in maintenance mode and new registrations are disabled on the Zoo until this evening.  More news later…

Beaten to the punch

Our own paper covering the discovery of Hanny’s Voorwerp is still working it’s way through the refereeing process. We’ve come up against a referee who really understands the subject and it’s taking time to put right our numerous missteps and to make everything clear. A new version will be submitted in the next couple of days, so hopefully you’ll be able to read it soon.

In the meantime, a group of Dutch radio astronomers have published a paper reporting their own results which is accepted and available online. They were kind enough to discuss it with us, and add some of the team to the list of authors – and they’ll be blogging here next week to tell you about what they’ve done.

It still hurts to be beaten to publication, but at least they’re friendly and it’s another sign of how this remarkable object has captured people’s attention.
