Title: Oceans Of Data And Rosetta Stones: Understanding How The First Galaxies Formed
Date (JST): Thu, Apr 02, 2015, 13:30 - 14:30
Place: Seminar Room A
Abstract: I will begin by giving an overview of the Spitzer Large Area Survey with Hyper-Suprime-Cam (SPLASH), a 3.8 square degree survey of the COSMOS and SXDS fields. I will show early results on the evolution of the star forming galaxy main sequence, the galaxy mass function and galaxy clustering at 4<z<6 and what this teaches us about early galaxy formation. Next, I will show ALMA C[II] 158um and dust continuum maps of ten normal z~6 galaxies selected from the SPLASH data as “Rosetta Stones”. These observations show us that the properties of the Interstellar Medium in galaxies are significantly evolving from z~6 to z~4, which must be accounted for when studying early galaxy formation. Finally, I will discuss the statistically robust tools I am developing to analyze the next generation of survey data from Euclid, WFIRST, and LSST and how this will help us find the next set of “Rosetta Stones”.
