Abstract : Near - infrared observations have been obtained for a large sample of dwarf irregular galaxies, dwarf elliptical and blue compact dwarf galaxies. Near infrared photometry was obtained for radio sources discovered in a deep VLA radio survey. Near infrared observations were also obtained for the first brightest galaxy in a sample of nearby clusters. A large redshift survey, using the 21-cm hydrogen line, of dwarf galaxies in the northern hemisphere has been completed. Work has been done to understand the stellar populations and star formation are presently occurring. Keywords: Astronomy.
