High mass X-ray binaries are among the brightest X-ray sources in the Milky Way, as well as
in nearby Galaxies. Thanks to their highly variable emissions and complex phenomenology …

With the advent of more sensitive all-sky instruments, the transient universe is being probed
in greater depth than ever before. Taking advantage of available resources, we have …

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 …

We perform the first systematic search of all NICER archival observations of black hole (and
candidate) low-mass X-ray binaries for signatures of reverberation. Reverberation lags …

We report on deep, coordinated radio and X-ray observations of the black hole X-ray binary
XTE J1118+ 480 in quiescence. The source was observed with the Karl G. Jansky Very …

We present a multi-epoch hard X-ray analysis of Cygnus X-1 in its soft state based on four
observations with the Nuclear Spectroscopic Telescope Array (NuSTAR). Despite the basic …

We analyze five epochs of Neutron star Interior Composition Explorer (NICER) data of the
black hole X-ray binary MAXI J1820+ 070 during the bright hard-to-soft state transition in its …

The black hole binary Cygnus X-1 was observed in late 2012 with the Nuclear
Spectroscopic Telescope Array (NuSTAR) and Suzaku, providing spectral coverage over …

Here we study a 1–200 keV energy spectrum of the black hole binary Cygnus X-1 taken with
NuSTAR and Suzaku. This is the first report of a NuSTAR observation of Cyg X-1 in the …

Aims. We probe the high-energy (> 60 MeV) emission from the black hole X-ray binary
system, Cygnus X-1, and investigate its origin. Methods. We analyzed 7.5 yr of data by Fermi …
