Pinpointing the near-infrared location of Sgr A* by correcting optical distortion in the NACO imager
P. M. Plewa, S. Gillessen, F. Eisenhauer +8
Near-infrared observations of stellar orbits at the Galactic Center provide conclusive evidence for a massive black hole associated with the compact radio source Sgr A*. The astrom…
3D adaptive mesh refinement simulations of the gas cloud G2 born within the disks of young stars in the Galactic Center
M. Schartmann, A. Ballone, A. Burkert +8
The dusty, ionized gas cloud G2 is currently passing the massive black hole in the Galactic Center at a distance of roughly 2400 Schwarzschild radii. We explore the possibility of…
Circumstellar discs in Galactic centre clusters: Disc-bearing B-type stars in the Quintuplet and Arches clusters
Andrea Stolte, Benjamin Hussmann, Christoph Olczak +7
We investigate the circumstellar disc fraction as determined from L-band excess observations of the young, massive Arches and Quintuplet clusters residing in the central molecular…
