Since their discovery, Ultraluminous X-ray sources (ULXs) have attracted attention due to their combination of extreme luminosities and extra-nuclear locations. However, they are a fairly rare phenomenon, and attempts to investigate the general properties of the population have been hindered by a relative lack of known sources. Here, we present a large catalogue of ULX candidates including 655 detections of 475 discrete sources, based on the 2XMM Serendipitous Survey. To demonstrate the… Expand

Ultraluminous X-ray Sources in Andromeda Galaxy: Two Recent Discoveries and their Implications
Ultraluminous X-ray sources are believed to be associated with X-ray binaries, in which an accreting black hole generates X-ray luminosities in excess of 10 erg/s. The nature of the companion starExpand
Polarization of AGN in UV spectral range
We present the review of some new problems in cosmology and physics of stars in connection with future launching of WSO. We discuss three problems. UV observations of distant z>6 quasars allow toExpand
Periodic Fast Radio Bursts from Luminous X-ray Binaries
The discovery of periodicity in the arrival times of the fast radio bursts (FRBs) poses a challenge to the oft-studied magnetar scenarios. However, models that postulate that FRBs result fromExpand
Population Synthesis of Ultraluminous X-ray Sources with Magnetized Neutron Stars
A model of population of ultraluminous X-ray sources with magnetised neutron stars (NULX) in a spiral galaxy with the star formation history similar to that in the thin disc of Milky Way is computedExpand


One hundred fifty-four discrete non-nuclear ultraluminous X-ray (ULX) sources, with spectroscopically determined intrinsic X-ray luminosities greater than 10 39 ergs s � 1 , are identified in 82Expand
Ultraluminous X-Ray Sources in External Galaxies
We investigate models for the class of ultraluminous nonnuclear X-ray sources (i.e., ultraluminous compact X-ray sources [ULXs]) seen in a number of galaxies and probably associated with star-formingExpand
X-ray observations of ultraluminous X-ray sources
Abstract Ultraluminous X-ray sources (ULXs) are amongst the most intriguing of X-ray source classes. Their extreme luminosities—greater than 1039 erg s−1 in the 0.3–10 keV band alone—suggest eitherExpand
Maps of low-inclination nearby galaxies in Sloan Digitized Sky Survey u – g, g – r, and r – i colors are used to determine whether ultraluminous X-ray sources (ULXs) are predominantly associated withExpand
XMM–Newton observations of the brightest ultraluminous X-ray sources
We present an analysis of 13 of the best quality ultraluminous X-ray source (ULX) data sets available from XMM‐Newton European Photon Imaging Camera (EPIC) observations. We utilize the highExpand
The ultraluminous state
We revisit the question of the nature of ultraluminous X-ray sources (ULXs) through a detailed investigation of their spectral shape, using the h ighest quality X-ray data available in the XMM-NewtonExpand
Slim-Disk Model for Ultraluminous X-Ray Sources
The ultraluminous X-ray sources (ULXs) are unique in exhibiting moderately bright X-ray luminosities, LX ~ 1038-1040 ergs s-1, and relatively high blackbody temperatures, Tin ~ 1.0-2.0 keV. From theExpand
Suzaku Observations of M 82 X-1 : Detection of a Curved Hard X-Ray Spectrum
A report is presented on Suzaku observations of the ultra-luminous X-ray source X-1 in the starburst galaxy M 82, made three times in 2005 October for an exposure of � 30 ks each. The XIS signalsExpand
X-ray reflection in a sample of X-ray bright ultraluminous X-ray sources
We apply a reflection-based model to the best available XMM-Newton spectra of X-ray bright ultraluminous X-ray sources (NGC 1313 X-1, NGC 1313 X-2, M 81 X-6, Holmberg IX X-1, NGC 5408 X-1 andExpand
The Resolved Fraction of the Cosmic X-Ray Background
We present the X-ray source number counts in two energy bands (0.5-2 and 2-10 keV) from a very large source sample: we combine data of six different surveys, both shallow wide-field and deepExpand
