Journal ArticleDOI
Explaining the Moderate UV/X-Ray Correlation in AGN
TL;DR: In this paper , the authors show that a low UV/X-ray correlation is well expected in the case of an X-ray illuminated accretion disk, when the dynamic variability of the Xray source is taken into account.
Journal ArticleDOI
Active galaxy 4U 1344-60: did the relativistic line disappear?
Jiri Svoboda,Stefano Bianchi,Matteo Guainazzi,Giorgio Matt,Enrico Piconcelli,Vladimir Karas,Michal Dovciak +6 more
TL;DR: In this article, the spectroscopic results of new data obtained with the Suzaku satellite and compare them with the previous XMM-Newtonobservation were presented, showing that no evidence of the relativistic reflection is present in the spectra.
Journal ArticleDOI
Spectral and polarization properties of black hole accretion disc emission: including absorption effects
R. Taverna,Lorenzo Marra,Stefano Bianchi,Michal Dovciak,Rene W. Goosmann,Frédéric Marin,Giorgio Matt,W. Zhang +7 more
TL;DR: In this paper, the authors generalize the problem by calculating the ionization structure of a surface layer of the disc with the public code CLOUDY, and then by determining the polarization properties of the emerging radiation using the Monte Carlo code STOKES.

TL;DR: This list of astronomers from around the world selected for this year’s USRA/Goddard Space Flight Center “Star Trek” competition highlights the importance of knowing the orbit of the Sun, as well as the scientists’ backgrounds, training, and research priorities.
Journal ArticleDOI
Eclipsing the innermost X-ray emitting regions in AGN
TL;DR: In this article, a relativistic X-ray spectral model for occultation events was developed and theoretical predictions on the different observables that can be inferred by studying Xray eclipses in simulated XMM-Newton data.
