HI observations of nearby galaxies. IV. More dwarf galaxies in the southern sky.

Abstract (from CDS):

In this paper we present HI observations of nearby galaxies from two more lists of the Karachentsev catalog of candidates for nearby dwarf galaxies in the southern sky. Observations north of declination -31° were performed with the 100-m radio telescope at Effelsberg. Data for more southern galaxies were taken from HIPASS (www.atnf.csiro.au/research/multibeam). This sample is a supplement to the list of 94 southern dwarf galaxy candidates (1998A&AS..127..409K) located in the same declination range around the known Local Volume galaxies (i.e. galaxies within 10Mpc, LV hereafter). We observed 17 galaxies not observed in the previous sample; and all 67 candidate dwarf galaxies from the SERC EJ sky survey (Karachentsev et al., 2000A&AS..146..359K) and 81 objects from a supplementary list of candidate dwarf galaxies (Karachentseva & Karachentsev, 2000A&AS..146..359K). This yields a total of 165 (=17+67+81) galaxies. Overall we have a detection rate of 48%. The sample of detected galaxies has the following median parameters: radial velocity VLG=1127km/s, HI line width W50=59km/s, absolute blue magnitude MBT0=-14.4mag, linear diameter A0=4.0kpc, hydrogen mass-to-luminosity ratio 1.6M/L. The sample of known galaxies within the Local Volume increased from 179 in 1979 (Kraan-Korteweg & Tammann, 1979AN....300..181K) to 387 now. This corresponds to an increase in total luminosity of 22%. The known HI mass in the LV increased by 25%; the relative HI content MHI/LB increased from 0.21 to 0.26 for the whole volume. However we still might have missed half of the dwarf galaxies in the Local Volume.
