One of a Handful in the Universe: Confirming a Wolf Rayet X-ray Binary Candidate in NGC 253
Abstract
With Chandra, we have discovered a candidate Wolf Rayet X-ray Binary (WR XRB) in NGC 253 as part of a NuSTAR-Chandra campaign. WR XRBs represents a rarely-observed instance of an progenitor system for a BH-BH merger of the type that emits gravitational waves detectable by Advanced LIGO. This particular source was present in an archival Chandra dataset and had previously not been recognized as a WR XRB candidate. We discuss the implications for this source as well as serendipitous searches for time-variable X-ray phenomena.
