Broadband X-ray Spectroscopy of the Unique ULX P13 in NGC7793
Abstract
We request an XMM (50 ks) + NuSTAR (100 ks) ToO observation of the ULXP13 in NGC7793 during its ultraluminous regime (Lx > 2e39 erg/s). Thedynamical mass constraint available for this source requires it to besuper-Eddington at these luminosities, making it a key laboratory forunderstanding this exotic mode of accretion. These observations willprovide the first hard X-ray detection of this source, and provide avital point of comparison with a known super-Eddington accretor for therest of the ULX population with broadband X-ray observations, which iscurrently missing. P13 is currently the only source that can providethis link. Our ToO will be triggered by the 12x1 ks Swift monitoringadditionally requested as part of this proposal.
