Bright X-ray flares from Sgr A*
G. D. Karssen, M. Bursa, A. Eckart +4
We address a question whether the observed light curves of X-ray flares originating deep in galactic cores can give us independent constraints on the mass of the central supermassi…
Infrared-excess Source DSO/G2 Near the Galactic Center: Theory vs. Observations
Michal Zajacek, Andreas Eckart, Florian Peissker +2
Based on the monitoring of the Dusty S-cluster Object (DSO/G2) during its closest approach to the Galactic Center supermassive black hole in 2014 and 2015 with ESO VLT/SINFONI, we…
Polarized light from Sgr A* in the near-infrared -band
B. Shahzamanian, A. Eckart, M. Valencia-S. +13
We present a statistical analysis of polarized near-infrared (NIR) light from Sgr A*, the radio source associated with the supermassive black hole at the center of the Milky Way. T…
Monitoring the Dusty S-Cluster Object (DSO/G2) on its Orbit towards the Galactic Center Black Hole
M. Valencia-S., A. Eckart, M. Zajacek +23
We analyse and report in detail new near-infrared (1.45 - 2.45 microns) observations of the Dusty S-cluster Object (DSO/G2) during its approach to the black hole at the center of t…
The infrared K-band identification of the DSO/G2 source from VLT and Keck data
Andreas Eckart, M. Horrobin, S. Britzen +24
A fast moving infrared excess source (G2) which is widely interpreted as a core-less gas and dust cloud approaches Sagittarius A* (SgrA*) on a presumably elliptical orbit. VLT K_s-…
The Galactic Center as a Paradigm for Low Luminosity Nuclei? The K-band identification of the DSO/G2 source from VLT and Keck data
Andreas Eckart, S. Britzen, M. Horrobin +27
The super-massive 4 million solar mass black hole (SMBH) SgrA* shows flare emission from the millimeter to the X-ray domain. The nucleus of the Milky Way has properties (stellar cl…
