HI observations of dwarf galaxies in voids.

HUCHTMEIER W.K., HOPP U. and KUHN B.

Abstract (from CDS):

We report HI-observations of a sample of 43 optically selected galaxies from the Heidelberg-void project. Only emission line galaxies have been selected. The HI-detection rate was 67%. The observed sample is a mix in late-type morphology objects with a spread in luminosity. They were compared to other samples with similar selection effects and mixtures. The detected galaxies have a high HI content and their MHI/LB values are systematically higher than expected from a local field comparison sample. Especially, for the 10 dwarfs in our sample (8.2≤logLB≤9.2) which appear to be highly isolated, a mean MHI/LB=1.8 was derived which is higher than for all comparison samples, including those with the same restricted luminosity range. We discuss a trend in our data between the relative HI-content and the surrounding galaxy density holding from very high densities (Virgo-cluster) to the very isolated objects at the rims of the voids. We also present HI observations of 7 HII-galaxies of the University of Michigan (UM) sample.
