In an earlier post I mentioned the conferences that I was attending this summer: 3 of them in the space of about 7 weeks, which is a little crazy. I’m now back from the last of them so it’s time to update you on what happened. One thing I learned, that I should have known earlier, is that four and a half hours is not a long-enough red-eye flight on which to get a reasonable amount of sleep!
At CASCA 2012 I went to quite a few talks, although unfortuately I missed a number of talks given by Western grad students. Many talks were excellent: in particular I found the Qilak Award (for contributions to education and public outreach) lecture by John Percy to be so full of good advice that I tweeted most of it. I also picked up some interesting gossip, such as the fact that the Canada-France-Hawaii Telescope was closed for over two months after its dome shutter failed, and talked to some colleagues about a number of things, including science. And we went to the Rothney Observatory just outside of Calgary, from which we completely failed to see any of the Venus transit. (It’s not the conference organizers’ fault that it was cloudy.)
The Great Andromeda Galaxy meeting was much more science-focused for me. Most of the talks were longer and there were plenty of reports from various big projects. This was also a “centennial meeting” celebrating the life and career of the late Martin Schwarzschild, so there were some historical talks as well. Someone pointed out on Twitter that it was interesting to watch the change between the Apple standard background image of M31 (which, interstingly, is missing one of M31’s satellite galaxies) and whichever picture of the galaxy was contained in the talk. The most popular one seemed to be the GALEX ultraviolet image. The meeting ended with a talk by David Spergel where he both summarized the meeting and told us a little about the “gift” of two unused space telescopes to NASA. He couldn’t give full details since some of us in the room were foreigners. Really. Ask me about ITAR if you don’t believe this.
The Gemini Science and Users’ meeting just finished last Friday. This one featured a number of invited talks on a number of topics from exoplanets to high-redshift galaxies. I think these were uniformly excellent, which pleased me since I was in charge of the committee picking the speakers! This meeting also featured updates on a number of the Gemini instruments, including the upcoming FLAMINGOS-2 (which has had some problems but is nearly ready to go), Gemini South Adaptive Optics Imager, Gemini Planet Imager. Also in the works is a fiber-optic pipeline between the Gemini telescope and the CFHT, so that the ESPaDOnS spectrograph can be fed with light from the larger Gemini-North telescope. The question of what instruments to build next also came up for discussion, and I think it’s fair to say there was some controversy about this, with some people arguing strongly for a very wide wavelength-coverage spectrograph, GIROS, and others wanting a fuller discussion of the options. Gemini also has a new incoming director (who, in this small world of astronomy, happens to be a sometime collaborator of mine) and the consensus is that he’s got quite the opportunity and challenge ahead of him.
