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…

Experimental Indicators of Accretion Processes in Active Galactic Nuclei

A. Eckart, M. Valencia-S., B. Shahzamanian +19

Bright Active Galactic Nuclei are powered by accretion of mass onto the super massive black holes at the centers of the host galaxies. For fainter objects star formation may signif…

Emergence of spacetime dynamics in entropy corrected and braneworld models

A. Sheykhi, M. H. Dehghani, S. E. Hosseini

A very interesting new proposal on the origin of the cosmic expansion was recently suggested by Padmanabhan [arXiv:1206.4916]. He argued that the difference between the surface deg…

Friedmann equations in braneworld scenarios from emergence of cosmic space

A. Sheykhi, M. H. Dehghani, S. E. Hosseini

Recently, it was argued that the spacetime dynamics can be understood by calculating the difference between the degrees of freedom on the boundary and in the bulk in a region of sp…
