Coupling between the accreting corona and the relativistic jet in the microquasar GRS 1915+ 105
Accreting black holes emit highly collimated radio jets expanding at speeds approaching
light speed. Some of these jets appear to be expanding at superluminal speeds due to …

vKompth: a variable Comptonization model for low-frequency quasi-periodic oscillations in black hole X-ray binaries
Low-mass X-ray binaries (LMXBs) show strong variability over a broad range of time-scales.
The analysis of this variability, in particular of the quasi-periodic oscillations (QPO), is key to …

The NICER “Reverberation Machine”: A Systematic Study of Time Lags in Black Hole X-Ray Binaries
We perform the first systematic search of all NICER archival observations of black hole (and
candidate) low-mass X-ray binaries for signatures of reverberation. Reverberation lags …

The evolution of the corona in MAXI J1535−571 through type-C quasi-periodic oscillations with Insight-HXMT
Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients can appear when
the source is in the low-hard and hard-intermediate states. The spectral-timing evolution of …

Phase-resolved spectroscopy of a quasi-periodic oscillation in the black hole X-ray binary GRS 1915+105 with NICER and NuSTAR
E Nathan, A Ingram, J Homan… - Monthly Notices of …, 2022 - academic.oup.com
Quasi-periodic oscillations (QPOs) are often present in the X-ray flux from accreting stellar-
mass black holes (BHs). If they are due to relativistic (Lense–Thirring) precession of an inner …

A variable corona for GRS 1915+ 105
Most models of the low-frequency quasi-periodic oscillations (QPOs) in low-mass X-ray
binaries (LMXBs) explain the dynamical properties of those QPOs. On the other hand, in …
