Astronomy Colloquium

  I will discuss MASSIVE, an ambitious new integral-field survey of the ~100 most massive galaxies within 100 Mpc.  Using integral-field spectroscopy covering 200 pc to 20 kpc scales, we are studying the assembly history of massive galaxies from the supermassive black holes at the center to the dark matter halos on large scales. I will then discuss black hole scaling relations over a large range in galaxy mass, using MASSIVE observations at the high end and megamaser disk galaxies at low mass. If time permits, I will discuss progress on survey planning for the Prime Focus Spectrograph.
