The origin of optical emission lines in the soft state of X-ray binary outbursts: The case of MAXI J1820+070 [PDF]
Monthly notices of the Royal Astronomical Society, 2023 The optical emission line spectra of X-ray binaries (XRBs) are thought to be produced in an irradiated atmosphere, possibly the base of a wind, located above the outer accretion disc.

Intermittent properties of the quasi-periodic oscillations of MAXI J1820+070 revealed by Insight-HXMT [PDF]
Astronomy & Astrophysics, 2023 We investigate the dynamical properties of low frequency quasi-periodic oscillations (QPOs) observed from the black hole X-ray binary MAXI J1820+070 during the early part of its 2018 outburst, when the system was in a bright hard state.

MAXI J1820+070 X-ray spectral-timing reveals the nature of the accretion flow in black hole binaries [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Black hole X-ray binaries display significant stochastic variability on short time-scales (0.01–100 seconds), with a complex pattern of lags in correlated variability seen in different energy bands.

The Donor of the Black Hole X-Ray Binary MAXI J1820+070 [PDF]
Astrophysical Journal, 2022 We estimate the parameters of the donor of the accreting black hole binary MAXI J1820+070. The measured values of the binary period, rotational and radial velocities, and constraints on the orbital inclination imply the donor is a subgiant with the mass ...

Multiwavelength observations of MAXI J1820+070 during its outburst decay and subsequent mini-outburst [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We present results from quasi-simultaneous multiwavelength observations of the Galactic black hole X-ray transient MAXI J1820+070 during the decay of the 2018 outburst and its entire subsequent mini-outburst in March 2019. We fit the X-ray spectra with
