Coordinated X-ray and UV absorption within the accretion disk wind of the active galactic nucleus PG 1126-041
M. Giustini, P. Rodríguez Hidalgo, J. N. Reeves +14
Accretion disk winds launched close to supermassive black holes (SMBHs) are a viable mechanism to provide feedback between the SMBH and the host galaxy. We aim to characterize the…
Tormund's return: Hints of quasi-periodic eruption features from a recent optical tidal disruption event
E. Quintin, N. A. Webb, S. Guillot +8
Quasi-periodic eruptions (QPEs) are repeating thermal X-ray bursts associated with accreting massive black holes, the precise underlying physical mechanisms of which are still uncl…
Alive and kicking: A new QPE phase in GSN 069 revealing a quiescent luminosity threshold for QPEs
G. Miniutti, M. Giustini, R. Arcodia +4
X-ray quasi-periodic eruptions (QPEs) are intense repeating soft X-ray bursts from the nuclei of nearby galaxies. Their physical origin is still largely unconstrained, and several…
Quasi-periodic eruptions from impacts between the secondary and a rigidly precessing accretion disc in an extreme mass-ratio inspiral system
Alessia Franchini, Matteo Bonetti, Alessandro Lupi +7
X-ray quasi-periodic eruptions (QPEs) represent a recently discovered example of extreme X-ray variability associated with supermassive black holes. These are high-amplitude bursts…
