Further spectroscopic studies of the Bootes region - two more galaxies in the void
Description
Redshifts are reported for 40 galaxies in the direction of the Bootes void identified in the Case Low-Dispersion Northern Sky Survey, List IV. Two new emission-line galaxies have been discovered in the void. The density of bright emission-line galaxies in the void is estimated to be a factor of 3 + or - 2 lower than the density of similar galaxies in the field. The galaxies are distributed uniformly with distance from the void center. A previously reported correlation between Case IV redshift estimates and measured redshifts is confirmed. Data for previously observed IRAS galaxies are combined with the present results to compared the luminosity distribution of IRAS galaxies to that for emission-line galaxies. The IRAS luminosity distribution contains a greater fraction of intrinsically bright galaxies than the emission-line galaxy distribution. 25 references
