Super-Eddington Accretion through a Multiwavelength Lens: Searching for Counterparts of Ultraluminous X-ray Sources
R. Amato, M. Bachetti, R. Soria +8
Ultraluminous X-ray sources (ULXs) represent the closest and most accessible laboratories to study sustained super-Eddington accretion onto compact objects. Over the past decade, t…
The population of hyperluminous X-ray sources as seen by XMM-Newton
Roberta Amato, Erwan Quintin, Hugo Tranin +7
Ultraluminous and hyperluminous X-ray sources (ULXs and HLXs) are among the brightest astrophysical objects in the X-ray sky. While ULXs most likely host stellar-mass compact objec…
A new candidate pulsating ULX in NGC 7793
Erwan Quintin, Natalie Webb, Andrés Gúrpide +2
We report here the discovery of NGC 7793 ULX-4, a new transient ultraluminous X-ray source (ULX) in NGC 7793, a spiral galaxy already well known for harbouring several ULXs. This n…
Long-term X-ray spectral evolution of Ultraluminous X-ray sources: implications on the accretion flow geometry and the nature of the accretor
Andrés Gúrpide, Olivier Godet, Filippos Koliopanos +2
The discovery of pulsations in several Ultraluminous X-ray sources (ULXs) demonstrated that a fraction of ULXs are powered by super-Eddington accretion onto neutron stars (NSs). Th…
