Monitoring dusty sources in the vicinity of Sgr A*
F. Peißker, S. E. Hosseini, M. Zajacek +5
We trace several dusty infrared sources on their orbit around the supermassive black hole (SMBH) SgrA* in the center of our galaxy. We give an overview of known and unknown sources…
Radio spectral index distribution of SDSS-FIRST sources across optical diagnostic diagrams
Michal Zajaček, Gerold Busch, Mónica Valencia-S. +7
A detailed understanding of how the activity of a galactic nucleus regulates the growth of its host is still missing. To understand the activity and the types of accretion of super…
Bow shock sources close to the Galactic centre
Michal Zajacek, Andreas Eckart, Seyedeh Elaheh Hosseini
We provide an up-to-date summary of the current observational and theoretical studies of stellar bow-shock sources close to the Galactic centre. The symmetry axis of a bow shock pr…
Super-Massive Black Hole mass estimation from bright flares
Vladimir Karas, Michal Bursa, Michal Dovciak +4
Super-Massive Black Holes reside in galactic nuclei, where they exhibit episodic bright flares due to accretion events. Taking into account relativistic effects, namely, the boosti…
Near-infrared observations of star formation and gas flows in the NUGA galaxy NGC 1365
Nastaran Fazeli, Gerold Busch, Monica Valencia-S. +4
In the framework of understanding the gas and stellar kinematics and their relations to AGNs and galaxy evolution scenarios, we present spatially resolved distributions and kinemat…
