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…
Polarization constraints on the X-ray corona in Seyfert Galaxies: MCG-05-23-16
A. Marinucci, F. Muleri, M. Dovčiak +97
We report on the first observation of a radio-quiet Active Galactic Nucleus (AGN) using polarized X-rays: the Seyfert 1.9 galaxy MCG-05-23-16. This source was pointed with the Imag…
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…
SRGA J181414.6-225604: A new Galactic symbiotic X-ray binary outburst triggered by an intense mass loss episode of a heavily obscured Mira variable
Kishalay De, Ilya Mereminskiy, Roberto Soria +24
We present the discovery and multi-wavelength characterization of SRGA J181414.6-225604, a Galactic hard X-ray transient discovered during the ongoing SRG/ART-XC sky survey. Using…
