I suspect this is finally the last post relating to the AAS meeting, but I wanted to share the slides from my talk last Friday. Please note that these results are officially provisional! Talks at the AAS are just 5 minutes long (with so many astronomers it’s hard to find space) and I was definitely pushing my luck cramming this much in. As you’ll see, I’m not really one for lots of words on slides so I’ll write a brief commentary between them.
Obligatory title slide complete with names. Sorry Anze for missing out the Berkeley logo.
Pretty Sloan galaxies in need of classification; there were then a couple of slides showing the site design which I’ll presume you’re familiar with.
The picture is from BBC News ‘most emailed’. People seemed to find our competing articles funny.
Note that the first six hours showed nothing (as the server had melted). There was then a slide about the weightings, which Anze has already blogged about.
Look, it works!
The last sentence means that the result was statistically significant, although we now know that’s down to human bias and not the Universe.
I’m still very excited about getting observing time.
and about the blue ellipticals. The Milky Way forms stars at a rate of about 1 solar mass per year, so these things are really going some.
The next few slides have the provisional version on Steven’s results. This shows the fraction of galaxies which are elliptical at a range of densities, from the middle of nowhere on the left to the centre of galaxy clusters on the right.
Same thing, but showing red galaxies as well as ellipticals. People are surprised to be reminded that red doesn’t necessarily mean elliptical.
And the same thing, but for blue ellipticals and red spirals. It’s particularly interesting that red spirals seem to prefer a particular density.
And that’s it. There were some positive questions, mostly about future plans, and then it was on to the next talk.
