    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-1.
