On the nature of ultraluminous X-ray sources

Uspekhi Fizicheskih Nauk, 2019
Abstract Ultraluminous X-ray sources (ULXs) that are located in external galaxies exhibit X-ray luminosities exceeding those of the brightest black holes in the Milky Way and the Local Group galaxies by hundreds or even thousands of times.

The demographics of ultraluminous X‐ray sources

Astronomische Nachrichten, 2011
AbstractResults of recent statistical studies of the population of ultraluminous X‐ray sources are presented. Special emphasis is placed on the outcome of a complete survey of 140 nearby galaxies hosting 114 ULXs. It is shown that ULXs are preferentially associated with young star‐forming regions but not necessarily with massive young clusters, that ...

Ultraluminous X-ray sources with the SKA

2015
The discovery almost three decades ago of non-nuclear, point-like X-ray sources with X-ray luminosities LX ≥ 3 × 1039 erg s−1 revolutionized the physics of black hole accretion. If of stellar origin, such Ultraluminous X-ray sources (ULXs) would have to accrete at super-Eddington rates in order to reach the observed high X-ray luminosities ...
