We present an XMM-Newton observation of the highly polarized low-surface brightness supernova remnant G107.5–1.5 , discovered with the Canadian Galactic Plane Survey ( CGPS ) .
We do not detect diffuse X-ray emission from the SNR and set an upper limit on the surface brightness of \sim 2 \times 10 ^ { 30 } erg arcmin ^ { -2 } s ^ { -1 } , at an assumed distance of 1.1 kpc .
We found eight bright point sources in the field , including the ROSAT source 1RXS J225203.8+574249 near the centre of the radio shell .
Spectroscopic analysis of some of the embedded point sources , including the ROSAT source , has been performed , and all eight sources are most likely ruled out as the associated neutron star , primarily due to counterpart bright stars in optical and infrared bands .
Timing analysis of the bright point sources yielded no significant evidence for pulsations , but , due to the timing resolution , only a small part of the frequency space could be searched .
An additional ten fainter point sources were identified in the vicinity of the SNR .
Further X-ray observation of these and the region in the vicinity of the radio shell may be warranted .
