Abstract Neutron Star Interior Composition Explorer has a comparatively low background
rate, but it is highly variable, and its spectrum must be predicted using measurements …

All disc-accreting astrophysical objects produce powerful disc winds. In compact binaries
containing neutron stars or black holes, accretion often takes place during violent outbursts …

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 …

Accretion disks around compact objects are expected to enter an unstable phase at high
luminosity. One instability may occur when the radiation pressure generated by accretion …

The Galactic black hole transient GRS 1915+ 105 is famous for its markedly variable X-ray
and radio behaviour, and for being the archetypal galactic source of relativistic jets. It …

After 26 yr in outburst, the black hole X-ray binary GRS 1915+ 105 dimmed considerably in
early 2018; its flux dropped sharply in mid-2019, and it has remained faint ever since. This …

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 …

We present the discovery of eclipses in the X-ray light curves of the X-ray binary Swift J1858.
6–0814. From these, we find an orbital period of s (≈ 21.3 h) and an eclipse duration of s (≈ …

We present the discovery of an optical accretion disk wind in the X-ray transient Swift J1858.
6-0814. Our 90-spectrum data set, taken with the 10.4 m Gran Telescopio Canarias …

IGR J17407− 2808 is an enigmatic and poorly studied X-ray binary that was recently
observed quasi-simultaneously with NuSTAR and XMM-Newton. In this paper we report the …
