Aims. During the last~ 50 years, the population of black hole candidates in X-ray binaries
has increased considerably, with 59 Galactic objects being detected in transient low-mass X …

The mass spectrum of stellar mass black holes (BHs) is highly uncertain. Dynamical mass
measurements are available only for few (∼ 10) BHs in X-ray binaries, while theoretical …

X-ray studies of stellar mass black holes in X-ray binaries and mass-accreting supermassive
black holes in Active Galactic Nuclei have achieved a high degree of maturity and have …

We present a systematic study of the orbital inclination effects on black hole transients fast
time-variability properties. We have considered all the black hole binaries that have been …

We report on a first census of Galactic black hole X-ray binary (BHXRB) properties with the
second data release (DR2) of Gaia, focusing on dynamically confirmed and strong …

We compile a catalogue of low-mass and high-mass X-ray binaries, some recently reported
binaries that likely host a neutron star (NS) or a black hole (BH), and binary pulsars (a pulsar …

Quasi-periodic oscillations (QPOs) with frequencies from∼ 0.05-30 Hz are a common
feature in the X-ray emission of accreting black hole binaries. As the QPOs originate from the …

After the discovery of powerful relativistic jets from Narrow-Line Seyfert 1 Galaxies, and the
understanding of their similarity with those of blazars, a problem of terminology was born …

ABSTRACT The International Gamma-Ray Astrophysics Laboratory (INTEGRAL), launched
in 2002, continues its successful work in observing the sky at energies E> 20 keV. The …
