On the role and origin of nonthermal electrons in hot accretion flows
Andrzej Niedzwiecki, Agnieszka Stepnik, Fu-Guo Xie
We study the X-ray spectra of tenuous, two-temperature accretion flows using a model involving an exact, Monte Carlo computation of the global Comptonization effect as well as gene…
X-ray spectra of hot accretion flows
Andrzej Niedzwiecki, Fu-Guo Xie, Agnieszka Stepnik
We study radiative properties of hot accretion flows in a general relativistic model with an exact treatment of global Comptonization, developed in our recent works. We note a stro…
X-ray emission from hot accretion flows
Andrzej Niedzwiecki, Fu-Guo Xie, Agnieszka Stepnik
Radiatively inefficient, hot accretion flows are widely considered as a relevant accretion mode in low-luminosity AGNs. We study spectral formation in such flows using a refined mo…
Gamma-ray emission from proton-proton interactions in hot accretion flows
Andrzej Niedzwiecki, Fu-Guo Xie, Agnieszka Stepnik
We present a model of gamma-ray emission through neutral pion production and decay in two-temperature accretion flows around supermassive black holes. We refine previous studies of…
