Abstract

We present Data Release 2 of the Point Source Catalogue created from a series of previously constructed radio-continuum images of M31 at lambda=20cm (nu=1.4GHz) from archived VLA observations. In total, we identify a collection of 916 unique discrete radio sources across the field of M31. Comparing these detected sources to those listed by Gelfand et al. (2004ApJS..155...89G, Cat. J/ApJS/155/89) at lambda=92cm, the spectral index of 98 sources has been derived. The majority (73%) of these sources exhibit a spectral index of {alpha}<-0.6, indicating that their emission is predominantly non-thermal in nature, which is typical for background objects and Supernova Remnants (SNRs).
