Broadband nuclear emission in two radio-loud BAL quasars
M. Kunert-Bajraszewska, K. Katarzynski, A. Janiuk
The X-ray weakness of broad absorption line (BAL) quasars in comparison to non-BAL objects is possibly caused by the absorption of X-ray emission by the shielding material near the…
Oscillating shocks in the low angular momentum flows as a source of variability of accreting black holes
Petra Suková, Agnieszka Janiuk
We derive the conditions for shock formation in a quasi-spherical, slightly rotating flows. We verify the results of semi-analytical, stationary calculations with the time evolutio…
Interplay between heartbeat oscillations and wind outflow in microquasar IGR J17091-3624
Agnieszka Janiuk, Mikolaj Grzedzielski, Fiamma Capitanio +1
During the bright outburst in 2011, the black hole candidate IGR J17091-3624 exhibited strong quasi-periodic flare-like events (on timescales of tens of seconds) in some characteri…
Nucleosynthesis of elements in gamma ray bursts engines
Agnieszka Janiuk
We consider the gamma ray burst (GRB) central engine that is powered by the collapse of a massive rotating star or compact binary merger. The engine is a hot and dense accretion di…
