Radio and X-ray Observations of the Northwestern Rim of the Galactic Supernova Remnant G156.2+5.7
Abstract
We present a broadband X-ray spectral study of the northwestern rim of the Galactic supernova remnant (SNR) G156.2+5.7. This SNR is a member of the class of sources which feature a significant non-thermal component to their observed X-ray emission. Recent X-ray observations have established that the non-thermal X-ray emission is broadly localized to the northwestern portion of the SNR but a true understanding of the process responsible for this emission has yet to be achieved. To investigate a possible synchrotron origin for this emission, we are analyzing archival X-ray observations made of this northwestern rim with XMM-Newton and RXTE as well as radio observations made with the 21-Meter Morehead State University Radio Telescope and Space Tracking Antenna. Initial results will be presented and discussed.
