Active galaxy 4U 1344-60: did the relativistic line disappear?

Jiri Svoboda, Stefano Bianchi, Matteo Guainazzi +4

X-ray bright active galactic nuclei represent a unique astrophysical laboratory for studying accretion physics around super-massive black holes. 4U 1344-60 is a bright Seyfert gala…

Modeling optical and UV polarization of AGNs II. Polarization imaging and complex reprocessing

F. Marin, R. W. Goosmann, C. M. Gaskell +2

We model the spectropolarimetric signature resulting from the radiative coupling between the innermost parts of active galactic nuclei (AGNs). We use a new public version of STOKES…

X-ray polarimetry as a new tool to discriminate reflection from absorption scenarios -- Predictions for MCG-6-30-15

F. Marin, R. W. Goosmann, M. Dovciak +5

We present modelling of X-ray polarisation spectra emerging from the two competing scenarios that are proposed to explain the broad Fe Kα line in the Seyfert 1 galaxy MCG-6-30-15.…

Modeling the optical/UV polarization while flying around the tilted outflows of NGC 1068

Frederic Marin, Rene W. Goosmann, Michal Dovciak

Recent modeling of multi-waveband spectroscopic and maser observations suggests that the ionized outflows in the nuclear region of the archetypal Seyfert-2 galaxy NGC 1068 are incl…

QPO in RE J1034+396: model constraints from observed trends

B. Czerny, P. Lachowicz, M. Dovciak +3

We analyze the time variability of the X-ray emission of RE J1034+396, an active galactic nucleus with the first firm detection of a quasi-periodic oscillations (QPO). Based on the…
