TL;DR: The 3XMM-DR5 dataset as mentioned in this paper contains 565,962 X-ray detections from the European Space Agency X-Ray observatory XMM-Newton.
Journal ArticleDOI
A mass of less than 15 solar masses for the black hole in an ultraluminous X-ray source
Christian Motch,Manfred W. Pakull,Roberto Soria,Fabien Grisé,Grzegorz Pietrzyński,Grzegorz Pietrzyński +5 more
TL;DR: The results demonstrate that in P13, soft thermal emission and spectral curvature are indeed signatures of supercritical accretion, and by analogy, ultraluminousX-ray sources with similar X-ray spectra and luminosities can be explained by super critical accretion onto massive stellar-mass black holes.
Journal ArticleDOI
A 300-parsec-long jet-inflated bubble around a powerful microquasar in the galaxy NGC 7793
TL;DR: It is reported that the large nebula S26 in the nearby galaxy NGC 7793 is powered by a black hole with a pair of collimated jets, similar to the famous Galactic source SS433, but twice as large and a few times more powerful.
Journal ArticleDOI
