The Wind Dynamics of Super-Eddington Sources in FRADO
Mohammad-Hassan Naddaf, Bożena Czerny, Michal Zajaček
We perform non-hydrodynamical 2.5D simulations to study the dynamics of material above accretion disk based on the disk radiation pressure acting on dust. We assume a super-accreti…
Black-hole activity feedback across vast scales
Michal Zajaček, Bożena Czerny, Rainer Schödel +2
Both observational and theoretical studies of black-hole activity or active galactic nucleus (AGN) feedback have been ongoing since the first indication of supermassive black holes…
Non-thermal emission from fall-back clouds in the Broad-Line Region of Active Galactic Nuclei
Ana Laura Müller, Mohammad-Hassan Naddaf, Michal Zajaček +3
The spectra of active galactic nuclei exhibit broad-emission lines that presumably originate in the Broad-Line Region (BLR) with gaseous-dusty clouds in a predominantly Keplerian m…
Mid-Infrared studies of dusty sources in the Galactic Center
Harshitha K. Bhat, Nadeen B. Sabha, Michal Zajaček +5
Mid-Infrared (MIR) images of the Galactic center show extended gas and dust features along with bright IRS sources. Some of these dust features are a part of ionized clumpy streame…
Stellar transits across a magnetized accretion torus as a mechanism for plasmoid ejection
Petra Suková, Michal Zajaček, Vojtěch Witzany +1
The close neighbourhood of a supermassive black hole contains not only the accreting gas and dust but also stellar-sized objects, such as late-type and early-type stars and compact…
First observed interaction of the circumstellar envelope of an S-star with the environment of Sgr A*
Florian Peißker, Basel Ali, Michal Zajaček +7
Several publications highlight the importance of the observations of bow shocks to learn more about the surrounding interstellar medium and radiation field. We revisit the most pro…
