资源简介：
The detection of pulsating ultraluminous X-ray sources (PULXs) has led to aparadigm shift for the field the key questions now revolve around thedemographics of ULXs (black holes vs neutron stars) and the details of theiraccretion physics. The detection of more PULXs is critical to answering bothquestions. We have therefore mined the recent Walton et al. (2022)multi-mission ULX catalogue with the intention of finding new PULX candidates. Here we propose a 111 ks deep observation of an extreme ULX (L(x) > 10^40erg/s) in NGC 3631 with both the characteristic hard X-ray spectrum of a PULXand a high enough flux to make a sensitive accelerated pulsation search viable.
