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 …

It is believed that stellar black holes (BHs) can be formed in two different ways: Either a
massive star collapses directly into a BH without a supernova (SN) explosion, or an …

We use very long baseline interferometry to measure the proper motions of three black hole
X-ray binaries (BHXBs). Using these results together with data from the literature and Gaia …

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 report new radio observations of a sample of 36 neutron star (NS) X-ray binaries, more
than doubling the sample in the literature observed at current-day sensitivities. These …

We present the radio and X-ray monitoring campaign of the 2019/2020 outburst of MAXI
J1348–630, a new black hole X-ray binary (BH XRB) discovered in 2019 January. We …

We present multiwavelength fast timing observations of the black hole X-ray binary MAXI
J1820+ 070 (ASASSN-18ey), taken with the Karl G. Jansky Very Large Array (VLA) …

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 …

We present results from six epochs of quasi-simultaneous radio,(sub-) millimetre, infrared,
optical, and X-ray observations of the black hole X-ray binary MAXI J1535− 571. These …

In outburst, neutron star X-ray binaries produce less powerful jets than black holes at a given
X-ray luminosity. This has made them more difficult to study as they fade towards …
