Black holes in binary systems execute patterns of outburst activity where two characteristic X-
ray states are associated with different behaviours observed at radio wavelengths. The hard …

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 present intermediate-resolution spectroscopy of the optical counterpart to the black hole
X-ray transient MAXI J1820+ 070 (= ASASSN-18ey) obtained with the OSIRIS spectrograph …

Abstract We present time-resolved 10.4 m Gran Telescopio Canarias and 4.2 m William
Herschel Telescope intermediate resolution spectroscopy of the X-ray transient MAXI …

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 nature and geometry of the accretion flow in the low/hard state of black hole binaries is
currently controversial. While most properties are generally explained in the truncated …

The black hole transient MAXI J1820+ 070 displayed optical P Cyg profiles and other wind-
related emission line features during the hard state of its discovery outburst. We present …

Disc winds are a common feature in accreting astrophysical systems on all scales. In active
galactic nuclei (AGNs) and accreting white dwarfs (AWDs), specifically, radiation pressure …

We present 12 epochs of optical spectroscopy taken across the discovery outburst of the
black hole (BH) candidate MAXI J1803− 298 with the Gran Telescopio Canarias and Very …

Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst.
Based on the X-ray spectrum and variability, this evolution can be divided into three …
