HI in Local Group Analogs: What does it Tell Us about Galaxy Formation?

Pisano, Daniel; Barnes, David G; Gibson, Bradley K; Staveley-Smith, L.; Freeman, Kenneth; Kilborn, Virginia A


We present the results of our HI survey of six loose groups of galaxies analogous to the Local Group. The survey was conducted using the Parkes telescope and the Australia Telescope Compact Array to produce a census of all the gas-rich galaxies and potential analogs to the high-velocity clouds (HVCs) within these groups down to MHI ≤ 107 M⊙ as a test of models of galaxy formation. We present the HI mass function and halo mass function for these analogous groups and compare them with the Local...[Show more]
