Comparison of HI and optical redshifts of galaxies - The impact of redshift uncertainties on spectral line stacking
Accurate optical redshifts will be critical for spectral co-adding techniques used to extract detections from below the noise level in ongoing and upcoming surveys for HI, which will extend our current understanding of gas reservoirs in galaxies to lower column densities and higher redshifts. We hav...
