One hundred fifty-four discrete non-nuclear ultraluminous X-ray (ULX) sources, with spectroscopically determined intrinsic X-ray luminosities greater than 1039 ergs s-1, are identified in 82 galaxies observed with Chandra's Advanced CCD Imaging Spectrometer. Source positions, X-ray luminosities, and spectral and timing characteristics are tabulated. Statistical comparisons between these X-ray properties and those of the weaker discrete sources in the same fields (mainly neutron star and stellar… 

XMM-Newton Observations of Ultraluminous X-Ray Sources in Nearby Galaxies

We examined X-ray spectral and timing properties of ultraluminous X-ray sources (ULXs) in nearby galaxies in XMM-Newton archival data. There appear to be three distinct classes of spectra. One class

A Catalog of Hyper-luminous X-Ray Sources and Intermediate-mass Black Hole Candidates out to High Redshifts

Hyper-luminous X-ray sources (HLXs; LX > 1041 erg s−1) are off-nuclear X-ray sources in galaxies and strong candidates for intermediate-mass black holes (IMBHs). We have constructed a sample of 169

X-Ray and Optical Eclipses in Ultraluminous X-Ray Sources as Possible Indicators of Black Hole Mass

Ultraluminous X-ray sources (ULXs) with 1039 ergs s-1 ≲ LX < 1041 ergs s-1 have been discovered in great numbers in external galaxies with ROSAT, Chandra, and XMM-Newton. The central question

Ultraluminous X-ray sources in the Chandra and XMM-Newton era

Ultraluminous X-ray sources out to z ~ 0.3 in the COSMOS field

Context. Using Chandra observations we identified a sample of seven off-nuclear X-ray sources in the redshift range z = 0.072–0.283, located within optically bright galaxies in the COSMOS Survey. All

Ultraluminous X-Ray Sources

Ultraluminous X-ray sources (ULXs) were identified as a separate class of objects in 2000 based on data from the Chandra X-Ray Observatory. These are unique objects: their X-ray luminosities exceed

New flaring of an ultraluminous X-ray source in NGC 1365

Based on X-ray luminosity and spectral arguments, it is suggested that this accreting black hole in the Fornax galaxy NGC 1365 has a likely mass ∼50-150M ⊙ (even without accounting for possible beaming).

2XMM ultraluminous X-ray source candidates in nearby galaxies

Ultraluminous X-ray sources (ULXs) are some of the most enigmatic X-ray bright sources known to date. It is generally accepted that they cannot host black holes as large as those associated with

Ultraluminous X-ray sources: a deeper insight into their spectral evolution

We select a sample of nearby Ultraluminous X-ray sources with long XMM-Newton observations and analyse all the available XMM-Newton data using both X-ray spectral fitting techniques and


We have re-examined the most luminous X-ray sources in the starburst galaxy NGC 4631, using XMM-Newton, Chandra, and ROSAT data. The most interesting source is a highly variable supersoft



Chandra X-Ray Observations of the Spiral Galaxy M81

A Chandra X-Ray Observatory ACIS-S imaging observation is used to study the population of X-ray sources in the nearby Sab galaxy M81 (NGC 3031). A total of 177 sources are detected with 124 located

The Nature of Ultraluminous Compact X-Ray Sources in Nearby Spiral Galaxies

Studies were made of ASCA spectra of seven ultraluminous compact X-ray sources in nearby spiral galaxies: M33 X-8, M81 X-6, IC 342 source 1, Dwingeloo 1 X-1, NGC 1313 source B, and two sources in NGC

A Chandra X-Ray Study of NGC 1068. II. The Luminous X-Ray Source Population

We present an analysis of the compact X-ray source population in the Seyfert 2 galaxy NGC 1068, imaged with a ~50 ks Chandra observation. We find a total of 84 compact sources on the S3 chip, of

The Lack of Very Ultraluminous X-Ray Sources in Early-Type Galaxies

We have searched for ultraluminous X-ray sources (ULXs) in a sample of 28 elliptical and S0 galaxies observed with Chandra. We find that the number of X-ray sources detected at a flux level that

Ultraluminous X-ray source populations in normal galaxies: a preliminary survey with Chandra

We present results of a Chandra survey of the ultraluminous X-ray sources (ULX) in 13 normal galaxies, in which we combine source detection with X-ray flux measurement. 22 ULX were detected, i.e.

X-Ray Spectroscopic Evidence for Intermediate-Mass Black Holes: Cool Accretion Disks in Two Ultraluminous X-Ray Sources

We have analyzed an XMM-Newton observation of the nearby spiral galaxy NGC 1313, which contains two "ultraluminous" X-ray (ULX) sources. We measure isotropic luminosities of LX = 2.0 × 1040 ergs s-1

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-forming

Chandra X-Ray Observations of NGC 1316 (Fornax A)

We report the results of the Chandra ACIS subarcsecond resolution X-ray observation of the archetypal merger radio galaxy NGC 1316 (Fornax A). We confirm the presence of fine substructures in the hot

Three LINERs under the Chandra X-Ray Microscope
