“Observations of Molecular Gas in High-Redshift Galaxies”

Dr. Andrew Baker

Fully understanding the evolutionary state of a galaxy requires that we characterize its gas reservoir, of which the molecular component represents the mass directly available for star formation. I will discuss radio observations of molecular gas in two populations of star-forming galaxies at high redshift-- Lyman break galaxies and submillimeter galaxies-- and what we can learn from them. I will highlight recent work with the "Zpectrometer" (a new, ultrawide bandwidth 26-38 GHz spectrometer for the 100m Green Bank Telescope) and prospects for future work with ALMA (the Atacama Large Millimeter/submillimeter Array).
