Census of the Galactic Centre early-type stars using spectro-imagery
T. Paumard, R. Genzel, J. P. Maillard +4
The few central parsecs of the Galaxy are known to contain a surprising population of early-type stars, including at least 30 Wolf-Rayet stars and luminous blue variables (LBV), id…
An infrared imaging search for low-mass companions to members of the young nearby beta Pic and Tucana/Horologium associations
Ralph Neuh"auser, E. W. Guenther, J. Alves +3
We present deep high dynamic range infrared images of young nearby stars in the Tucana/Horologium and beta Pic associations, all ~ 10 to 35 Myrs young and at ~10 to 60 pc distance.…
Inward Bound: Studying the Galactic Centre with NAOS/CONICA
T. Ott, R. Schoedel, R. Genzel +25
We report on the first results obtained using adaptive optics measurements of the Galactic Centre done with NAOS/CONICA.
Imaging and spectroscopy of DENIS-P J104814-395606
Ralph Neuhaeuser, Eike Guenther, Joao Alves +8
We obtained deep H- and K-band images of DENIS-P J104814-395606 using SofI and the speckle camera SHARP-I at the ESO-3.5m-NTT as well as QUIRC at the Mauna Kea 2.2m telescope betwe…
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 \…
