GAS-RICH DWARFS FROM THE 2ND PALOMAR SKY SURVEY .1. CATALOG AND CHARACTERISTICS

This project is a visual search for held dwarf galaxies using Second P alomar Sky Survey photographic plates. A morphologically selected samp le of 310 objects yielded 145 detections of true dwarfs within a redsh ift search window of 0 to 10,000 km s(-1). We confirm the low-mass, dw arf nature of the same by comparison of luminosity, isophotal size, H I mass and H I profile width distribution of other dwarf samples. The goal of this project is to use these newly discovered dwarf galaxies t o map large-scale structure as a test of biased galaxy formation. Init ial indicators are that the large-scale distribution of dwarf galaxies is identical to that of bright, high-mass galaxies, in contradiction to theory using biasing. The full analysis of the sample will be repor ted in the final paper of our series.
