Spectral Analysis of 1H0707-495 with XMM-Newton
T. Dauser, J. Svoboda, N. Schartel +6
We present the results of a 500 ksec long XMM-Newton observation and a 120 ksec long quasi-simultaneous Chandra observation of the Narrow Line Seyfert 1 galaxy 1H0707-495 performed…
Black hole accretion rings revealed by future X-ray spectroscopy
V. Sochora, V. Karas, J. Svoboda +1
Spectral features can arise by reflection of coronal X-rays on a black hole accretion disc. The resulting profile bears various imprints of strong gravitational field acting on the…
The flare model for X-ray variability of NGC 4258
T. Trzesniewski, B. Czerny, V. Karas +4
We study the variability mechanism of active galactic nuclei (AGN) within the framework of the flare model. To this end we examine the case of Seyfert/LINER galaxy NGC 4258, which…
Light bending scenario for accreting black holes in X-ray polarimetry
M. Dovciak, F. Muleri, R. W. Goosmann +2
We discuss a model of an X-ray illuminating source above an accretion disk of a rotating black hole. Within the so called lamp-post scheme we compute the expected (observed) polari…
Near-infrared polarimetry as a tool for testing properties of accreting super-massive black holes
M. Zamaninasab, A. Eckart, M. Dovciak +10
Several massive black holes exhibit flux variability on time scales that correspond to source sizes of the order of few Schwarzschild radii. We survey the potential of near-infrare…
