SUMMARY:Molecular gas\, AGNs\, star formation and galaxy evolution: a 
 local look at galaxies undergoing the transition\, Astronomy Colloquiu
 m\, Katherine Alatalo\, CALTECH
DESCRIPTION:Understanding the evolution of galaxies from starforming b
 lue cloud objects into quiescent red sequence galaxies has been revolu
 tionized by observations taken with the Herschel Space Observatory\, A
 LMA\, and CARMA\, allowing astronomers to probe both the cold dust and
  cold ISM in a large set of galaxies\, with unprecedented sensitivity.
   Observations of galaxies in molecular gas\, cold dust and the cool I
 SM (such as the [C II] line) have given us an unprecedented view of th
 e transition galaxies undergo to go from the blue starforming cloud to
  the red sequence.  Specifically\, I will discuss the role a compact g
 roup environment plays in this transition\, as well as discuss the unu
 sual case of NGC1266\, a local S0 galaxy that is expelling its interst
 ellar medium at a rate of 50 Msuns/yr\, over 100x the star formation r
 ate.  These example systems have the potential to provide local labora
 tories for understanding mechanisms that transition galaxies at higher
  redshift\, and put the roles of AGNs and mild interactions into the l
 arger context of galaxy evolution.
