TL;DR: In this paper, the authors reported radial-velocity measurements taken over two years of the Galactic B-type star, LB-1, and found that the motion of the B star and an accompanying Hα emission line require the presence of a dark companion with a mass of about 68 solar masses, which can only be a black hole.

TL;DR: Radial-velocity measurements of a Galactic B-type star show a dark companion that seems to be a black hole of about 68 solar masses, in a widely spaced binary system.
Journal ArticleDOI
Relativistic baryonic jets from an ultraluminous supersoft X-ray source

TL;DR: The unexpected presence of relativistic jets in a ULS challenges canonical theories of jet formation, but might be explained by a long-speculated, supercritically accreting black hole with optically thick outflows.
