Discovery of a Dense Association of Stars in the Vicinity of the Supermassive Black Hole Sgr A*
S. Elaheh Hosseini, Andreas Eckart, Michal Zajaček +3
We focus on a sample of 42 sources in the vicinity of the bow-shock source IRS 1W (N-sources), located at the distance of north-east of the supermassive black hole (SMBH)…
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…
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…
Constraining the accretion flow density profile near Sgr A* using the -band emission of the S2 star
S. Elaheh Hosseini, Michal Zajaček, Andreas Eckart +2
The density profile of the ambient medium around a supermassive black hole plays an important role in understanding the inflow-outflow mechanisms in the Galactic Centre. We constra…
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…
