X-ray Reflection as Diagnostic of Supermassive Black Hole Binary Properties
Julie Malewicz, Tamara Bogdanović, David R. Ballantyne +2
We investigate correlations between prominent features in the relativistic X-ray reflection spectrum emitted by an accreting supermassive black hole (SMBH) binary with the underlyi…
Joint XMM-Newton and NuSTAR Observations of Type I X-ray Bursts from the Dipping Low-Mass X-ray Binary 4U 1323-62
Tugba Boztepe, Tolga Guver, Ersin Gogus +4
In this study, we report partly simultaneous XMM-Newton and NuSTAR observations of the bursting, dipping low mass X-ray binary, 4U 1323-62 obtained in 2024. 4U 1323-62 is one of th…
The 2020 Superburst of 4U 1608-522 and its impact on the accretion disk
Tugba Boztepe, Tolga Guver, Elif Ece Devecioglu +9
Superbursts are rare events observed from bursting neutron star low mass X-ray binaries. They are thought to originate from unstable burning of the thick layer of Carbon on the sur…
Impact of Accretion Assumptions on Pulse Profile Modelling of Superburst Oscillations in 4U 1636-536
Yves Kini, Anna L. Watts, Tuomo Salmi +7
Modelling the coherent pulsations observed during thermonuclear bursts offers a valuable method to probe the poorly understood equation of state of dense and cold matter. Here we a…
A Comprehensive Study of Thermonuclear X-ray Bursts from 4U 1820-30 with NICER: Accretion Disk Interactions and a Candidate Burst Oscillation
Gaurava K. Jaisawal, Z. Funda Bostancı, Tuğba Boztepe +14
We present the results obtained from timing and spectral studies of 15 thermonuclear X-ray bursts from 4U 1820-30 observed with the Neutron Star Interior Composition Explorer (NICE…
Simulating the Collapse of a Thick Accretion Disk due to a Type I X-ray Burst from a Neutron Star
P. Chris Fragile, David R. Ballantyne, Thomas J. Maccarone +1
We use two-dimensional, general relativistic, viscous, radiation hydrodynamic simulations to study the impact of a Type I X-ray burst on a hot and geometrically thick accretion dis…
