The Evolution of Neutral Hydrogen Content in Galaxies as a Function of Redshift and Environment
Presented by Monica Sanchez (UNM)
Neutral Hydrogen (HI) in and around galaxies is an important diagnostic tool for understanding galaxy formation and evolution. One way to interpret the HI data is by measuring the HI mass function (HIMF), which is a measure of the space density of galaxies as a function of their HI mass. However, little is known about how the HIMF changes as a function of redshift, or how it is affected by environment. To address this, we are using the results of two separate ongoing HI surveys, CHILES and ALFAZOA, which uniquely probe HI in galaxies with complementary depth and sky coverage to detect HI galaxies in different environments and redshift ranges. I will describe both surveys and present new results, as well as discussion on future work.
