A multi-wavelength study of the western lobe of W50 powered by the Galactic microquasar SS 433
Abstract
W50 remains the only Galactic supernova remnant (SNR) confirmed to harbor a binary twin-jet microquasar: the powerful enigmatic source SS 433. Our extensive study of this fascinating SNR reveals two X-ray lobes distorting the radio shell, as well as non-thermal X-rays at the sites of interaction between the SS 433 eastern jet and the eastern lobe of the SNR shell. In the western lobe, we have evidence (from a multi-wavelength campaign) of an interaction site between the western jet of SS 433 and a dense medium. We will present our 75 ksec CHANDRA ACIS-I observation of the peak of W50-west targeted to 1) spatially resolve thermal and non-thermal X-ray emission from the shock-excited regions, and 2) spatially correlate the X-ray emission with the emission seen at infrared and radio wavelengths.
