Abstract
Hydrogen is the fuel for star formation, but relatively little is known about the role of cold gas in galaxy evolution. The COSMOS HI Large Extragalactic Survey (CHILES) is an on-going deep neutral hydrogen (HI) survey being conducted with the Very Large Array, probing a 0.5 degree region within the COSMOS field in the 21cm line of neutral hydrogen. CHILES is the first survey to observe HI in emission from redshift z=0 to z~0.5, which corresponds to a look-back time of ~ 5 Gyr. This allows us to observe the content, morphology and kinematics of HI in relation to stellar disks, and how it may have evolved over this period. Here, we present a simulation of the galaxy detections that could be made by the survey, based on multi-wavelength data from the COSMOS dataset in the VLA field of view.
