Searching for compact objects in SNRs G27.8+0.6 and G28.8+1.5.

MISANOVIC Z., KARGALTSEV O. and PAVLOV G.G.

Abstract (from CDS):

We analyzed XMM-Newton observations of two center-filled supernova remnants (SNRs), G27.8+0.6 and G28.8+1.5, to search for pulsars/pulsar wind nebulae (PWNe) and other types of neutron stars (NSs) associated with these remnants. We discovered a PWN candidate within the extent of the centrally peaked radio emission of G27.8+0.6. The X-ray morphology of the PWN candidate and its position with respect to the host SNR suggest that the alleged pulsar might be moving away from the SNR's center with a transverse velocity of around 100-200 km/s. The majority of the detected X-ray point sources in both fields are classified as main-sequence stars, based on their bright optical counterparts and relatively soft X-ray spectra. The remaining medium-hard and hard sources are most probably either active galactic nuclei or cataclysmic variables, although we cannot completely rule out the possibility that some of these sources are NSs.
