ALFALFA and WSRT Imaging of Extended H I Features in the Leo Cloud of Galaxies.


Abstract (from CDS):

We present ALFALFA H I observations of a well studied region of the Leo Cloud, which includes the NGC 3227 group and the NGC 3190 group. We detect optically dark H I tails and plumes with extents potentially exceeding 600 kpc, well beyond the field of view of previous observations. These H I features contain ∼40% of the total H I mass in the NGC 3227 group and ∼10% of the NGC 3190 group. We also present WSRT maps which show the complex morphology of the the extended emission in the NGC 3227 group. We comment on previously proposed models of the interactions in these group and the implications for the scale of group processing through interactions. Motivated by the extent of the H I plumes, we place the H I observations in the context of the larger loose group, demonstrating the need for future sensitive, wide field H I surveys to understand the role of group processing in galaxy evolution.
