X-ray disc reverberation modelling of the X-ray/UV/optical spectral/timing properties of Fairall 9
M. Polioudakis, M. Papoutsis, I. E. Papadakis +3
Multiwavelength monitoring surveys of active galactic nuclei (AGN) have revealed correlated variability observed in the X-ray, UV, and optical bands. X-ray reverberation, arising f…
Observation of A Solar Like Magnetic Reconnection Event in an AGN Corona with XRISM
Gal Vardi, Ehud Behar, Liyi Gu +14
The X-ray source in AGN is commonly referred to as the corona by analogy to stellar coronae. The similarities between the two suggest that the heating mechanism of AGN coronae is m…
A Suppressed Volumetric Rate of High-Luminosity Mid-Infrared Selected Tidal Disruption Events
Prajna Nair, Christos Panagiotou, Megan Masterson +4
Tidal Disruption Events (TDEs) serve as direct probes of the population of supermassive black holes in the center of galaxies and are nowadays regularly detected in optical wide-fi…
Discovery of Quasar Variability and Early Accretion Disk Signatures at Cosmic Dawn
Gene C. K. Leung, Anna-Christina Eilers, Christos Panagiotou +12
In the nearby universe, quasars are well known to exhibit variability in their brightness over time, offering a powerful tool to probe the physics of accretion onto the SMBH and di…
Delving into the depths of NGC 3783 with XRISM: V. Broad-band modeling of ionized outflows
Keqin Zhao, Jelle S. Kaastra, Liyi Gu +7
The Seyfert 1 galaxy NGC 3783 hosts a multiphase warm absorber (WA) that has been extensively studied in the X-ray band. High-resolution spectra from 2000-2001 revealed a complex o…
Persistence of the Millihertz X-ray Quasi-Periodic Oscillation in the Active Galactic Nucleus 1ES 1927+654
Megan Masterson, Erin Kara, William N. Alston +15
1ES 1927+654 is an extreme active galactic nucleus (AGN) that has defied our canonical expectations for how AGN appear across the electromagnetic spectrum and how they vary on shor…
