The local volume H I survey: galaxy kinematics.


Abstract (from CDS):

We present a detailed analysis of the neutral hydrogen kinematics of 12 nearby dwarf irregular galaxies observed as part of the Local Volume H I Survey conducted at the Australia Telescope Compact Array. For each galaxy we measure the disc parameters (inclination, position angle) and the H I rotation curve. Six galaxies in our sample (AM 0605-341, Argo Dwarf, ESO 059-G001, ESO 137-G018, ESO 174-G?001 and ESO 308-G022) have their atomic hydrogen distribution studied for the first time. AM 0605-341 was found to have an extension of redshifted H I which we propose is due to a tidal interaction with NGC 2188. There is evidence that ESO 215-G?009 has extraplanar H I gas. We also compare the global galaxy properties, in particular the integrated H I flux density and velocity widths of the observed H I spectra, with the results from the low angular resolution H I Parkes All Sky Survey. We discuss under what circumstances the 21 cm emission-line profile can accurately predict the galaxies rotation velocity, an observational parameter crucial to study the classical and baryonic Tully–Fisher relations.
