Bars side project
Dear Zooniverse users,
We’d like to re-draw [no pun intended!] your attention to the GalaxyZoo Google-powered Bar drawing website: http://www.icg.port.ac.uk/~hoyleb/bars/ simply log in with your Zooninverse username and password. Please note, this site works best using FireFox.
In this project, we ask for more specific observations and even drawing to be performed on a selection of galaxies. The sample size is relatively small, and 8000 [of the 8400] galaxies have been classified 5 times. The remaining 400 have been examined 6+ times.
We are starting to collate votes, for example we see some excellent agreement between users, e.g. See the picture below, which shows the bars as drawn on the above galaxy by different users, but we still need a few more classifications for each galaxy, to really be able to produce science.
One such science question we’d like to answer is, “How does the presence of a bar, affect the galaxies properties?”. GZoo allows us to study this question with 20- times more data than previously possible.
We’d also like to thank the GZ users for the hard work they have put into the site since it’s launch in October.
Ben Hoyle, on behalf of the GZ-bar drawing team
