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…
Kinematic Structure of the Galactic Center S-cluster
Basel Ali, Daria Paul, Andreas Eckart +7
We present a detailed analysis of the kinematics of 112 stars that mostly comprise the high velocity S-cluster and orbit the super massive black hole SgrA* at the center of the Mil…
Light and shadow in the Galactic Center - On the detection of the relativistic periastron shift of star S2 in the Galactic Center
A. Eckart, M. Parsa, E. Mossoux +11
We report on the nature of prominent sources of light and shadow in the Galactic Center. With respect to the Bremsstrahlung X-ray emission of the hot plasma in that region the Gala…
The Multifrequency Behavior of Sagittarius A*
A. Eckart, M. Zajacek, M. Parsa +15
The Galactic Center is the closest galactic nucleus that allows us to determine the multi-frequency behavior of the supermassive black hole counterpart Sagittarius A* in great deta…
Nuclear Activity and the Conditions of Star-formation at the Galactic Center
A. Eckart, M. Valencia-S., B. Shahzamanian +15
The Galactic Center is the closest galactic nucleus that can be studied with unprecedented angular resolution and sensitivity. We summarize recent basic observational results on Sa…
