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 …

Sixteen years of observations of black hole transients with the Rossi X-ray Timing Explorer,
complemented by other X-ray observatories and ground-based optical/infrared/radio …

We present the discovery of fast infrared/X-ray correlated variability in the black hole
transient GX 339− 4. The source was observed with subsecond time resolution …

Multiwavelength variability data, combined with spectral-timing analysis techniques,
provides information about the causal relationship between different physical components in …

The general picture that emerged by the end of 1990s from a large set of optical and X-ray,
spectral and timing data was that the X-rays are produced in the innermost hot part of the …

We study the effects of the mutual interaction of hot plasma and cold medium in black hole
binaries in their hard spectral state. We consider a number of different geometries. In …

We present a systemic analysis of all of the stellar-mass black hole binaries (confirmed and
candidate) observed by the Swift observatory up to 2010 June. The broad Swift bandpass …

A rapid timing analysis of Very Large Telescope (VLT)/ULTRACAM (optical) and RXTE (X-
ray) observations of the Galactic black hole binary GX 339− 4 in the low/hard, post-outburst …

Multiwavelength observations of Galactic black hole transients have opened a new path to
understanding the physics of the innermost parts of the accretion flows. While the processes …

We present observations of rapid (sub-second) optical flux variability in V404 Cyg during its
2015 June outburst. Simultaneous three-band observations with the ULTRACAM fast imager …
