Highest Redshift Image of Neutral Hydrogen in Emission: A CHILES Detection of a Starbursting Galaxy at z=0.376

Understand

Our current understanding of galaxy evolution still has many uncertainties associated with the details of accretion, processing, and removal of gas across cosmic time.

• The next generation of radio telescopes will image the neutral hydrogen (HI) in galaxies over large volumes at high redshifts, which will provide key insights into these processes.
• We are conducting the COSMOS HI Large Extragalactic Survey (CHILES) with the Karl G.
• Jansky Very Large Array, which is the first survey to simultaneously observe HI from z=0 to z~0.5.
