On the turbulent -disks and the intermittent activity in AGN
Agnieszka Janiuk, Bozena Czerny, Aneta Siemiginowska +1
We consider effects of the MHD turbulence on the viscosity during the evolution of the thermal-viscous ionization instability in the standard -accretion disks. We consider the p…
The origin of emission and absorption features in Ton S180 Chandra observations
A. Różańska, B. Czerny, A. Siemiginowska +2
We present new interpretation of Ton S180 spectrum obtained by {\it Chandra} Spectrometer (Low Energy Transmission Grating). Several narrow absorption lines and a few emission disk…
Universal spectral shape of AGN with high accretion rate
M. Nikolajuk, B. Czerny, A. Rozanska +1
The spectra of radio quiet and NLS1 galaxies show suprising similarity in their shape. They seem to scale only with the accretion rate but not with central black hole mass. We cons…
Universal spectral shape of high accretion rate AGN
B. Czerny, M. Nikolajuk, A. Rozanska +3
The spectra of quasars and NLS1 galaxies show surprising similarity in their spectral shape. They seem to scale only with the accretion rate. This is in contradiction with the simp…
