A magnetically-supported disk-corona model for Changing-Look AGN transitions
Marios Kouzis, Agata Różańska, Debora Lančová +2
Changing-Look Active Galactic Nuclei (CLAGN) undergo dramatic spectral and luminosity transitions on timescales of months to a few years -- orders of magnitude shorter than the vis…
X-ray view of dissipative warm corona in active galactic nuclei
B. Palit, A. Rozanska, P. O. Petrucci +8
In the X-ray spectra of AGNs, a noticeable excess of soft X-rays is typically detected beyond the extrapolation of the power-law trend observed between 2-10 keV. In the scenario of…
Radiation spectra of warm and optically thick coronae in AGN
P. -O. Petrucci, D. Gronkiewicz, A. Rozanska +9
A soft X-ray excess above the 2-10 keV power law extrapolation is generally observed in AGN X-ray spectra. Presently there are two competitive models to explain it: blurred ionized…
Warm and thick corona for magnetically supported disk in GBHB
Dominik Gronkiewicz, Agata Różańska
This paper is devoted to self-consistent modeling of the magnetically supported accretion disk with optically thick warm corona based on first principles. In our model, we consider…
