Description
Bright X-ray sources have been discovered in nearby galaxies since the 1970s and with the wide X-ray surveys carried out with Chandra, XMM-Newton, Swift and eRosita, many more have been revealed. Those X-ray sources with luminosities greater than ~1e39 erg/s, lying outside of the central nucleus, have been referred to as ultraluminous X-ray sources (ULXs) and for the brightest, with luminosities greater than ~1e41 erg/s, hyperluminous X-ray sources (HLXs). Over the last decade, these have been shown to be a diverse group of objects, ranging from stellar mass black holes accreting above and below the Eddington limit, neutron stars accreting (significantly) above the Eddington limit, as well as more massive black holes, including evidence for intermediate mass black holes. I will review recent advances in our understanding of these objects, along with other X-ray sources found in nearby galaxies.
