Radio-continuum study of the Nearby sculptor group galaxies. Part 1: NGC 300 at λ=20 cm

Abstract

A series of new radio-continuum (λ = 20 cm) mosaic images focused on the NGC300 galactic system were produced using archived observational data from the VLA and/or ATCA. These new images are both very sensitive (rms = 60 μJy) and feature high angular resolution (<10"). The most prominent new feature is the galaxy's extended radio-continuum emission, which does not match its optical appearance. Using these newly created images a number of previously unidentified discrete sources have been discovered. Furthermore, we demonstrate that a joint deconvolution approach to imaging this complete data-set is inferior when compared to an IMMERGE approach.
