The H I content of dark matter haloes at z ≈ 0 from ALFALFA

Abstract:

We combine information from the clustering of H I galaxies in the 100 per cent data release of the Arecibo Legacy Fast ALFA survey, and from the H I content of optically selected galaxy groups found in the Sloan Digital Sky Survey to constrain the relation between halo mass Mh and its average total H I mass content MH I. We model the abundance and clustering of neutral hydrogen through a halo-model-based approach, parametrizing the MH I(Mh) relation as a power law with an exponential mass cut...
