INTEGRAL is an ESA mission in fundamental astrophysics that was launched in October
2002. It has been in orbit for over 18 years, during which it has been observing the high …

Abstract The Chandra X-ray Observatory (Chandra) and the X-ray Multi-Mirror Mission (XMM-
Newton) continue to expand the frontiers of knowledge about high-energy processes in the …

Accretion of matter onto black holes is universally associated with strong radiative feedback
and powerful outflows. In particular, black-hole transients have outflows whose properties …

We present an analysis of the fundamental plane of black hole accretion, an empirical
correlation of the mass of a black hole (M), its 5 GHz radio continuum luminosity (νL ν), and …

Abstract Microquasars,,, are stellar-mass black holes accreting matter from a companion star
and ejecting plasma jets at almost the speed of light. They are analogues of quasars that …

ABSTRACT A comprehensive wideband spectral analysis of the brightest black hole X-ray
binary 4U 1543− 47 during its 2021 outburst is carried out for the first time using NICER …

Relativistic plasma jets are observed in many systems that host accreting black holes.
According to theory, coiled magnetic fields close to the black hole accelerate and collimate …

We present first results from a series of NuSTAR observations of the black hole X-ray binary
V404 Cyg obtained during its summer 2015 outburst, primarily focusing on observations …

Observational signatures of accretion disc winds have been found in a significant number of
low-mass X-ray binaries at either X-ray or optical wavelengths. The 2015 outburst of the …

Aims. V404 Cyg, Cyg X–3, V4641 Sgr, and GRS 1915+ 105 are among the brightest X-ray
binaries and display complex behavior in their multiwavelength emission. Except for Cyg X …
