HI observations of blue compact galaxies from the first and second Byurakan surveys.


Abstract (from CDS):

We present the results of a neutral hydrogen survey of 79 galaxies from a statistical sample of 88 Blue Compact Galaxies (BCGs) selected from the First and Second Byurakan objective prism surveys to have a HII region-like spectrum, an equivalent width of the [O III] λ5007 line larger than ∼50Å, and a velocity ≤6000km/s. The detection rate for the statistical sample is 74%. HI masses range between 4x107M and 5x109M with the HI mass distribution peaking at 3x108M. The full width at half-maximum of the HI profile varies between ∼30km/s and 160km/s, with a mean of ∼92km/s. These small widths are characteristic of dwarf galaxies. For comparison, we have also observed an additional 92 BCGs with weaker star formation and/or larger distances, and/or interesting astrophysical properties. These in general have larger widths and HI masses.
