High redshift radio quiet quasars -- exploring parameter space of accretion models. Part II: patchy corona model
M. A. Sobolewska, A. Siemiginowska, P. T. Zycki
We modeled the spectral energy distribution (SED) of high redshift radio quiet quasars (high-z RQQs). We computed spectra in a patchy corona geometry where an accretion disk extend…
High redshift radio quiet quasars - exploring the parameter space of accretion models. Part I: hot semi-spherical flow
M. A. Sobolewska, A. Siemiginowska, P. T. Zycki
Two families of models are currently considered to describe an accretion flow onto black holes and production of the observed X-ray radiation: (1) a standard cold accretion disk wi…
On the influence of relativistic effects on X-ray variability of accreting black holes
P. T. Zycki, A. Niedzwiecki
X-rays produced by compact flares co-rotating with a Keplerian accretion disc are modulated in time by Doppler effects. We improve on previous calculations of these effects by cons…
