A gas cloud on its way towards the super-massive black hole in the Galactic Centre
S. Gillessen, R. Genzel, T. K. Fritz +9
Measurements of stellar orbits provide compelling evidence that the compact radio source Sagittarius A* at the Galactic Centre is a black hole four million times the mass of the Su…
The star formation history of the Milky Way's Nuclear Star Cluster
O. Pfuhl, T. K. Fritz, M. Zilka +7
We present spatially resolved imaging and integral field spectroscopy data for 450 cool giant stars within 1\,pc from Sgr\,A*. We use the prominent CO bandheads to derive effective…
Line derived infrared extinction towards the Galactic Center
Tobias K. Fritz, Stefan Gillessen, Katie Dodds-Eden +7
We derive the extinction curve towards the Galactic Center from 1 to 19 micron. We use hydrogen emission lines of the minispiral observed by ISO-SWS and SINFONI. The extinction fre…
