From the FOURGE to the FIRE: Tracking Galaxy Evolution Over 12 Billion Years.

Kim-Vy Tran - Texas A&M University 

 

ZFOURGE and ZFIRE are deep observational surveys that track how galaxies assemble over cosmic time. ZFOURGE identifies approximately 70,000 objects up to redshifts of z~7 using a custom set of near-infrared imaging filters that provide high precision photometric redshifts. ZFIRE selects galaxies from ZFOURGE for spectroscopic follow-up to measure how baryons cycle between stars, winds, and the Inter-Stellar Medium (ISM) at z~2. Here I highlight results that include building a library of composite Spectral Energy Distributions and properties of galaxies in clusters at z~2.

Coffee and Donuts will be served at 2pm in 4054 McPherson Laboratory.
