Giant Metrewave Radio Telescope observations of neutral atomic hydrogen gas in the COSMOS field at z similar to 0.37

Rhee, Jonghwan; Lah, Philip; Chengalur, Jayaram N; Briggs, Franklin; Colless, Matthew


We present the results of H I spectral stacking analysis of Giant Metrewave Radio Telescope (GMRT) observations targeting the Cosmological Evolution Survey (COSMOS) field. The GMRT data cube contains 474 field galaxies with redshifts known from the zCOSMOS-bright 10 k catalogue. Spectra for the galaxies are co-added and the stacked spectrum allows us to make a ˜3σ measurement of the average H I mass. Using this average H I mass, along with the integral optical B-band luminosity of the galaxies...[Show more]
