galaxies like our own

My break from proposal-writing was a nice talk by Risa Wechsler (Stanford) about finding galaxy systems like that of the Milky Way plus Magellanic Clouds, both in the low-redshift SDSS sample and in huge n-body (dark-matter only) simulations. In both cases, having two massive satellites is rare, but she goes way beyond this, looking at what you can infer about the Milky Way from the presence of the Magellanic Clouds alone. Pretty neat stuff, though in the end she has a depressingly strong endorsement of the standard Lambda-CDM model.
