Optical outburst evolution of the transient black hole X-ray binary Swift J1727.8-1613: Disc response to jet ejections and late-outburst emergence of powerful disc winds

N. Castro Segura, K. Solomons, J. M. Corral-Santana +22

Swift J1727.81613 is a newly discovered transient low-mass X-ray binary harbouring a stellar-mass () black hole. We present state-resolved VLT/X-Shooter optical…

Unveiling the biconical geometry of the outflow in the ultraluminous X-ray source NGC 5204 X-1

S. Caserta, C. Pinto, T. Di Salvo +9

Ultraluminous X-ray sources (ULXs) are non-nuclear X-ray binary systems that exceed the Eddington luminosity for a 10 Msun black hole. The majority of these sources are thought to…

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…

Infrared Synchrotron Emission in the Soft State of GX 339-4 and the Mid-Infrared/X-ray Luminosity Plane of Black Hole X-ray Binaries

P. Gandhi, D. M. Russell, M. C. Baglio +33

Progress in understanding the growth of accreting black holes remains hampered by a lack of sensitive coordinated multiwavelength observations. In particular, the mid-infrared (MIR…

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…
