ANS UV observations of external galaxies. II. UV photometry of M 31, M33, M 81 M 101, NGC 2403 and several Zwicky galaxies.
Abstract
Five-colour area-integrated UV photometric results are given of 2.5×2.5 arcmin fields in the galaxies M31, M33, M81, M101 and NGC 2403. Most of these fields are centred on bright H II regions. The UV fluxes detected are generally representative of OB associations. The data for the nearby galaxies indicate radial gradients in brightness and colour within these galaxies. In addition, results are presented of a survey of Zwicky-type dwarf galaxies.
