A 330 MHz Survey for Pulsars and Supernova Remnants in M31
Abstract
In the radio band, supernova remnants (SNR) and pulsars are best identified at low frequencies due to their steep spectra. Motivated by this fact, we have carried out a deep 330 MHz observation of M31 using the VLA. Achieving a sensitivity of 0.6 mJy at 6 arcsec resolution over the entire optical disk of M31, we identified 405 distinct radio sources. While most of these are unresolved background radio galaxies, we found five SNR candidates, three pulsar wind nebula (PWN) candidates, and three pulsar candidates in our source list. The properties of these sources are discussed.
