S62 and S4711: Indications of a population of faint fast moving stars inside the S2 orbit -- S4711 on a 7.6 year orbit around Sgr~A*
Florian Peißker, Andreas Eckart, Michal Zajaček +2
We present high-pass filtered NACO and SINFONI images of the newly discovered stars S4711-S4715 between 2004 and 2016. Our deep H+K-band (SINFONI) and K-band (NACO) data show the S…
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…
S62 on a 9.9 yr Orbit around SgrA*
Florian Peißker, Andreas Eckart, Marzieh Parsa
We observe the S-cluster star S62 on its Keplerian orbit around the supermassive black hole in the center of our galaxy, SgrA*. The orbital time period of S62 around SgrA* is 9.9 y…
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…
A new bow-shock source with bipolar morphology in the vicinity of Sgr A*
F. Peißker, M. Zajacek, A. Eckart +3
Here we present a new bowshock blue-shifted source in the close vicinity of Sgr A* that we name X8. We use data-sets that are based on SINFONI observations with the Very Large Tele…
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…
