Wobbling around the clock: magnetically-driven quasi-periodic oscillations in pulsating ultraluminous X-ray sources
M. Veresvarska, M. Imbrogno, R. Amato +8
Ultraluminous X-ray sources (ULXs) are X-ray binary systems containing an accreting neutron star (NS) or black hole emitting at luminosities above the Eddington limit of a $10M_{\o…
QPEs as Lense-Thirring precession of super-Eddington flows
M. Middleton, A. Gurpide, T. M. Kwan +9
Quasi-periodic eruptions (QPEs) are a recently identified class of X-ray transient associated with tidal disruption events by supermassive black holes, and for which there are mult…
Rapid dimming followed by a state transition: a study of the highly variable nuclear transient AT 2019avd over 1000+ days
Yanan Wang, Dheeraj R. Pasham, Diego Altamirano +16
The tidal disruption of a star around a supermassive black hole (SMBH) offers a unique opportunity to study accretion onto a SMBH on a human-timescale. We present results from our…
Propeller states in locally super-critical ULXs
M. Middleton, A. Gurpide, D. J. Walton
An expected signature of the presence of neutron stars in the population of ultraluminous X-ray sources (ULXs) are large scale changes in X-ray luminosity, as systems reach spin eq…
Chandra probes the X-ray variability of M51 ULX-7: evidence of propeller transition and X-ray dips on orbital periods
G. Vasilopoulos, F. Koliopanos, F. Haberl +4
We report on the temporal properties of the ULX pulsar M51 ULX-7 inferred from the analysis of the 2018-2020 Swift/XRT monitoring data and archival Chandra data obtained over a per…
