Improved Constraints on Non-Kerr Deviations from Binary Black Hole Inspirals Using GWTC-4 Data
Debtroy Das, Swarnim Shashank, Cosimo Bambi
Gravitational wave (GW) observations of binary black hole (BBH) mergers provide a unique opportunity to probe the nature of spacetime in the strong-field and dynamical regime. We p…
Bright flare in the obscured state of GRS 1915+105 as seen by NICER and Swift
Shuaitongze Zhao, Honghui Liu, Menglei Zhou +3
We report time-resolved NICER and Swift X-ray spectroscopy of a bright flare from the black hole X-ray binary GRS 1915+105 during its obscured state, which is characterized by heav…
Testing non-circular black hole spacetime with X-ray reflection
Leda Gao, Swarnim Shashank, Cosimo Bambi
X-ray reflection spectroscopy is a powerful tool for testing the Kerr hypothesis and probing the strong gravity regime around accreting black holes. Most tests of General Relativit…
