ALMA Observations of Galaxy Evolution and Nuclear Activity

In the COSMOS survey we have now imaged the large scale structures out to redshift 3 using 200,000 galaxies with precision photometric redshifts. The evolution of the galaxies, their stellar masses and star formation activity is found to be strongly differentiated by environment. ALMA observations now also reveal strong evolution in the ISM masses as a function of redshift using a sample of 110 galaxies at z = 0.3 to 3. I also describe ALMA observations and theoretical work on ultra-luminous IR galaxies to determine the levels of starburst and AGN activities.

Refreshments will be served in CP 179 at 3:15 PM
