We present a broadband X-ray spectral study of the northwestern rim of the Galactic supernova remnant (SNR) G156.2+5.7 (RX J04591+5147). This SNR belongs to the class of sources which feature a significant non-thermal component to their observed X-ray emission. Recent X-ray observations of G156.2+5.7 have established that the non-thermal X-ray emission is broadly localized to the northwestern region of the SNR (where a radio bright rim is observed) but a true understanding of the physical process responsible for this emission has remained elusive. 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 observation made with the 21-Meter Morehead State University Radio Telescope and Space Tracking Antenna. Initial results will be presented and discussed.
