A mass of less than 15 solar masses for the black hole in an ultraluminous X-ray source

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

Probable intermediate-mass black holes in NGC 4559: XMM–Newton spectral and timing constraints

TL;DR: In this article, the authors examined X-ray and optical observations of two ultraluminous X-rays sources, X7 and X10 in NGC 4559, using XMM-Newton, Chandra and the Hubble Space Telescope (HST).
