J/A+AS/139/1 J/A+AS/139/1 HI in Byurakan blue compact galaxies T X Thuan V A Lipovetsky J -M Martin S A Pustilnik Astron. Astrophys. Suppl. Ser. 139 1 1999 1999A&AS..139....1T VII/172 : First Byurakan Survey (FBS) (Markarian+, 1989) Galaxies, radio H II regions H I data galaxies: compact galaxies: ISM galaxies: starburst radio lines: galaxies radio lines: ISM 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] {lambda}5007 line larger than ~50{AA}, and a velocity <=6000km/s. The detection rate for the statistical sample is 74%. HI masses range between 4x10^7^M_{sun}_ and 5x10^9^M_{sun}_ with the HI mass distribution peaking at 3x10^8^M_{sun}_. 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.

When CCD data was not available, Holmberg diameters were derived from measurements on the Palomar Sky Survey blue prints and the relation obtained by least-square fitting to the diameter data from a subsample of 48 of our BCGs with CCD photometry: d_H_(arcsec)=2.53d_PSS_(arcsec)+7.4".
