Explaining the moderate UV/X-ray correlation in AGN
Christos Panagiotou, Erin Kara, Michal Dovčiak
The UV/optical and X-ray variability of active galactic nuclei (AGN) have long been expected to be well correlated as a result of the X-ray illumination of the accretion disk. Rece…
The Host Galaxy and Rapidly Evolving Broad-line Region in the Changing-look Active Galactic Nucleus 1ES 1927+654
Ruancun Li, Luis C. Ho, Claudio Ricci +4
Changing-look active galactic nuclei (AGNs) present an important laboratory to understand the origin and physical properties of the broad-line region (BLR). We investigate follow-u…
A physical model for the UV/optical power spectra of AGN
Christos Panagiotou, Iossif Papadakis, Erin Kara +2
The UV/optical variability of AGN has long been thought to be driven by the X-ray illumination of the accretion disk. However, recent multi-wavelength campaigns of nearby Seyfert g…
