Constraints on Einstein-Maxwell dilaton-axion gravity from X-ray reflection spectroscopy
Ashutosh Tripathi, Biao Zhou, Askar B. Abdikamalov +2
Einstein-Maxwell dilaton-axion gravity is a string-inspired model arising from the low energy effective action of heterotic string theory and an important candidate as alternative…
Testing the Keplerian disk hypothesis using X-ray reflection spectroscopy
Ashutosh Tripathi, Biao Zhou, Askar B. Abdikamalov +3
The Novikov-Thorne model is the standard framework for the description of geometrically thin and optically thick accretion disks around black holes and is widely used to study the…
Shining X-rays on asymptotically safe quantum gravity
Biao Zhou, Askar B. Abdikamalov, Dimitry Ayzenberg +3
Asymptotically safe quantum gravity is a promising candidate scenario to provide a UV extension for the effective quantum field theory of Einstein's gravity. The theory has its fou…
