A review of quasi-periodic oscillations from black hole X-ray binaries: observation and theory
AR Ingram, SE Motta - New Astronomy Reviews, 2019 - Elsevier
Black hole and neutron star X-ray binary systems routinely show quasi-periodic oscillations
(QPOs) in their X-ray flux. Despite being strong, easily measurable signals, their physical …

Towards precision measurements of accreting black holes using X-ray reflection spectroscopy
Relativistic reflection features are commonly observed in the X-ray spectra of accreting black
holes. In the presence of high quality data and with the correct astrophysical model, X-ray …
