Improved model of X-ray emission from hot accretion flows
Andrzej Niedźwiecki, Michał Szanecki, Andrzej A. Zdziarski +1
We have developed an improved model of X-ray emission from optically thin, two-temperature accretion flows, \texttt{kerrflow}, using an exact Monte Carlo treatment of global Compto…
Comparison of spectral models for disc truncation in the hard state of GX 339-4
Marta A. Dziełak, Andrzej A. Zdziarski, Michał Szanecki +3
We probe models of disc truncation in the hard spectral state of an outburst of the well-known X-ray transient GX 339--4. We test a large number of different models of disc reflect…
Monte Carlo simulations of alternative sky observation modes with the Cherenkov Telescope Array
M. Szanecki, D. Sobczyńska, A. Niedźwiecki +2
We investigate possible sky survey modes with the Middle Sized Telescopes (MST, aimed at covering the energy range from 100 GeV to 10 TeV) subsystem of the Cherenkov Telescop…
Geomagnetic field and altitude effects on the performance of future IACT arrays
M. Szanecki, K. Bernlöhr, D. Sobczyńska +3
The performance of IACT's arrays is sensitive to the altitude and geomagnetic field (GF) of the observatory site. Both effects play important role in the region of the sub-TeV gamm…
Influence of the Geomagnetic Field on the IACT detection technique for possible sites of CTA observatories
M. Szanecki, K. Bernlöhr, D. Sobczyńska +3
We investigate the influence of the geomagnetic field (GF) on the Imaging Air Cherenkov Telescope technique for two northern (Tenerife and San Pedro Martir) and three southern (Sal…
Design Concepts for the Cherenkov Telescope Array
The CTA Consortium
Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray…
X/gamma-ray emission from hot accretion flows in AGNs
A. Niedzwiecki, F. -G. Xie, A. A. Zdziarski
We present preliminary results of our study of the impact of strong gravity effects on properties of the high energy radiation produced in accretion flows around supermassive black…
