Fifth Galaxy Zoo paper accepted – Everything you've ever wanted to know about Blue Early-type galaxies!
The peer-review process can sometimes take quite some time. One of the major motivations for doing Galaxy Zoo was to find galaxies that don’t quite fit into the neat picture of blue spirals and red ellipticals, and so one of the early Galaxy Zoo papers that we submitted was on the blue early-types/ellipticals fond by you guys. We initially submitted it last June for publication in the journal Monthly Notices of the Royal Astronomical Society.
In the time between last June and now, we went through two revisions after getting comments from an anonymous referee, and the third revision will now appear in a future issue of MNRAS. The paper will appear on the pre-print archive astro-ph on Monday, but if you can’t wait, you can also download the PDF here (warning: 7.6 MB!). If you want to see just the cool pictures, here’s the most exciting one:
These are all blue early-type galaxies with ongoing star formation. In fact, all of these have star formation rates (the rate at which young stars are being born) of more than 5 solar masses per year. That means each of these is churning out more young, blue, hot stars than our Milky Way galaxy!
Thanks to all of you for your clicks. This paper wouldn’t have been possible without Galaxy Zoo, and as always, we do acknowledge you on the first page of the paper:
