A Galactic SNR and its Quiescent Black Hole
Abstract
Radio and X-ray imaging of a newly discovered, transient X-ray binary reveals a coincident supernova remnant (SNR). High extinction inhibits determination of mass function for the binary at the current time, but every available diagnostic signals that the primary is a black hole. The structure of the SNR is particularly clear in radio, and similar to Cas A. However, the X-ray structure is not clearly revealed in a prior XMM-Newton snapshot observation. We request a 60~ks ACIS-I observation to reveal the X-ray morphology of the SNR, obtain basic age constraints from spectral modeling, and to detect the quiescent black hole.
