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 authors present the first direct observation of a magnetic reconnection flare in the X‑ray corona of the active galaxy NGC 3783, using XRISM and XMM‑Newton data that reveal a N…
Variability of the X-ray obscuring wind in Mrk 335 with XMM-Newton/RGS
Daniele Rogantini, Erin Kara, Luigi Gallo +10
The paper analyzes X‑ray spectra of the Seyfert galaxy Mrk 335 to characterize a multi‑phase, clumpy accretion‑disk wind that shows strong variability on day‑scale timescales and a…
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…
