New views on bar pattern speeds from the NUGA survey
V. Casasola, S. Garcia-Burillo, F. Combes +10
We present a review on bar pattern speeds from preliminary results in the context of the Nuclei of Galaxies (NUGA) project. The large variety of molecular circumnuclear morphologie…
A 600 minute near-infrared lightcurve of Sagittarius A*
L. Meyer, T. Do, A. Ghez +5
We present the longest, by a factor of two, near-infrared lightcurve from Sgr A* - the supermassive black hole in the Galactic center. Achieved by combining Keck and VLT data from…
GRAVITY: getting to the event horizon of Sgr A*
F. Eisenhauer, G. Perrin, W. Brandner +45
We present the second-generation VLTI instrument GRAVITY, which currently is in the preliminary design phase. GRAVITY is specifically designed to observe highly relativistic motion…
Encounters in the ONC - observing imprints of star-disc interactions
C. Olczak, S. Pfalzner, A. Eckart
The external destruction of protoplanetary discs in a clustered environment acts mainly due to two mechanisms: gravitational drag by stellar encounters and evaporation by strong st…
First VLTI infrared spectro-interferometry on GCIRS 7 - Characterizing the prime reference source for Galactic center observations at highest angular resolution
J. -U. Pott, A. Eckart, A. Glindemann +5
Investigating the environment of the massive black hole SgrA* at the center of the Galaxy requires the highest angular resolution available to avoid source confusion and to study t…
Near-infrared polarization images of the Orion proplyds
S. Rost, A. Eckart, T. Ott
We performed AO-assisted high-resolution imaging polarimetry on selected Orion proplyds close to the Trapezium stars in the J, H, and K bands. Differential polarimetric images of o…
