The very red afterglow of GRB 000418 - further evidence for dust extinction in a GRB host galaxy
S. Klose, B. Stecklum, N. Masetti +36
We report near-infrared and optical follow-up observations of the afterglow of the Gamma-Ray Burst 000418 starting 2.5 days after the occurrence of the burst and extending over nea…
Direct imaging search for planetary companions next to young nearby stars
R. Neuhaeuser, E. Guenther, W. Brandner +6
We report first results from our ground-based infrared imaging search for sub-stellar companions (brown dwarfs and giant planets) of young (up to 100 Myrs) nearby (up to 75 pc) sta…
Near-infrared adaptive optics observations of galaxy clusters: Abell 262 at z=0.0157, J1836.3CR at z=0.414, and PKS 0743-006 at z=0.994
W. Hackenberg, A. Eckart, R. I. Davies +5
We report on high angular resolution near-infrared (NIR) observations of three galaxy clusters at different redshifts using adaptive optics (AO). In the case of the barred spiral \…
Stellar Dynamics in the Galactic centre: Proper Motions and Anisotropy
R. Genzel, C. Pichon, A. Eckart +2
We report a new analysis of stellar dynamics in the Galactic centre, based on improved sky and LOS velocities for >100 stars within a few arcsec of SgrA*. Overall the motions do no…
