The study of ultraluminous X-ray sources (ULXs) has changed dramatically over the last
decade. In this review we first describe the most important observations of ULXs in various …

Ultraluminous X-ray sources (ULXs) are accreting black holes that may contain the missing
population of intermediate mass black holes or reflect super-Eddington accretion physics …

We study the impact of mass-transfer physics on the observable properties of binary black
hole populations that formed through isolated binary evolution. We used the POSYDON …

Based on a homogeneous set of X-ray, infrared and ultraviolet observations from Chandra,
Spitzer, GALEX and 2MASS archives, we study populations of high-mass X-ray binaries …

We study the electrodynamics of a kinetically mixed dark photon cloud that forms through
superradiance around a spinning black hole, and design strategies to search for the …

We present a new, multimission catalogue of ultraluminous X-ray source (ULX) candidates,
based on recent data releases from each of the XMM–Newton, Swift, and Chandra …

We revisit the question of the nature of ultraluminous X-ray sources (ULXs) through a
detailed investigation of their spectral shape, using the highest quality X-ray data available …

We present new Chandra observations that complete a sample of seventeen (17) luminous
infrared galaxies (LIRGs) with D< 60 Mpc and low Galactic column densities of NH≲ 5× 10 …

We present broadband X-ray analyses of a sample of bright ultraluminous X-ray sources
(ULX) with the goal of investigating the spectral similarity of this population to the known …

Although we are nearing a consensus that most ultraluminous X-ray sources (ULXs) below
1041 erg s− 1 represent stellar mass black holes accreting in a super-Eddington …
