Abstract
Hα observations centred on galaxies selected from the HI Parkes All-Sky Survey (HIPASS)typically show one and sometimes two star-forming galaxies within the ~15 arcmin beam of the Parkes 64 m HI detections. In our Survey for Ionization in Neutral Gas Galaxies (SINGG)we found 15 cases of HIPASS sources containing four or more emission line galaxies (ELGs). We name these fields Choir groups. In the most extreme case, we found a field with at least nine ELGs. In this paper, we present a catalogue of Choir group members in the context of the wider SINGG sample. The dwarf galaxies in the Choir groups would not be individually detectable in HIPASS at the observed distances if they were isolated, b..
