The infrared L'-band view of the Galactic Center with NAOS-CONICA at VLT
Y. Clénet, D. Rouan, E. Gendron +9
We report on Galactic Center L'-band observations made during NAOS/CONICA Science Verification. Colors of the inner 2" stars reveal an infrared excess of S2, the closest star to th…
Molecular Gas in the Lensed Lyman Break Galaxy cB58
Andrew J. Baker, Linda J. Tacconi, Reinhard Genzel +2
We have used the IRAM Plateau de Bure Interferometer to map CO(3-2) emission from the gravitationally lensed Lyman break galaxy MS1512-cB58. This is the first detection of a molecu…
Hot Very Small dust Grains in NGC 1068 seen in jet induced structures thanks to VLT/NACO adaptive optics
Daniel Rouan, Francois Lacombe, Eric Gendron +12
We present K, L and M diffraction-limited images of NGC 1068 obtained with NAOS+CONICA at VLT/YEPUN over a 3.5" field around the central engine. Hot dust (Tcol = 550-650 K) is foun…
Near-infrared flares from accreting gas around the supermassive black hole at the Galactic Centre
R. Genzel, R. Schoedel, T. Ott +5
Recent measurements of stellar orbits provide compelling evidence that the compact radio source Sagittarius A* at the Galactic Centre is a 3.6-million-solar-mass black hole. Sgr A*…
The Nuclear Gas Dynamics and Star Formation of NGC 7469
R. Davies, L. Tacconi, R. Genzel
We report interferometric radio CO2-1 observations at a resolution of 0.7", and 0.085" resolution adaptive optics K-band spectroscopy of the inner few arcseconds of NGC7469. The CO…
The European Large Area ISO Survey (ELAIS): The Final Band-merged Catalogue
ELAIS Consortium, :, M. Rowan-Robinson +16
We present the final band-merged ELAIS catalogue at 6.7, 15, 90, and 175 m, and the associated data at u,g,r,i,z,J,H,K, and 20cm. The origin of the survey, infrared and radio ob…
ISO spectroscopy of star formation and active nuclei in the luminous infrared galaxy NGC 6240
D. Lutz, E. Sturm, R. Genzel +4
We present Infrared Space Observatory mid- and far-infrared spectroscopy of the merging galaxy NGC 6240, an object presenting many aspects of importance for the role of star format…
A Geometric Determination of the Distance to the Galactic Center
F. Eisenhauer, R. Schoedel, R. Genzel +5
We report new astrometric and spectroscopic observations of the star S2 orbiting the massive black hole in the Galactic Center, which were taken at the ESO VLT with the adaptive op…
Stellar dynamics in the central arcsecond of our galaxy
R. Schoedel, R. Genzel, T. Ott +3
We present proper motions for 40 stars at projected distances from Sagittarius A* (Sgr A*). We find evidence on a level for radial anisotropy of the cluster…
SINFONI - Integral Field Spectroscopy at 50 milli-arcsecond resolution with the ESO VLT
F. Eisenhauer, H. Bonnet, R. Abuter +21
SINFONI is an adaptive optics assisted near-infrared integral field spectrometer for the ESO VLT. The Adaptive Optics Module (built by the ESO Adaptive Optics Group) is a 60-elemen…
The [CII] 158 um Line Deficit in Ultraluminous Infrared Galaxies Revisited
M. L. Luhman, S. Satyapal, J. Fischer +5
We present a study of the [CII] 157.74 um fine-structure line in a sample of 15 ultraluminous infrared (IR) galaxies (L_IR>10^12 Lsun; ULIRGs) using the Long Wavelength Spectromete…
The Stellar Cusp Around the Supermassive Black Hole in the Galactic Center
R. Genzel, R. Schoedel, T. Ott +12
We analyze deep near-IR adaptive optics imaging as well as new proper motion data of the nuclear star cluster of the Milky Way. The surface density distribution of faint stars peak…
The Galactic Center stellar cluster: The central arcsecond
R. Schoedel, R. Genzel, T. Ott +1
With 10 years of high-resolution imaging data now available on the stellar cluster in the Galactic Center, we analyze the dynamics of the stars at projected distances f…
The Position, Motion, and Mass of Sgr A*
M. J. Reid, K. M. Menten, R. Genzel +4
We report progress on measuring the position of Sgr A* on infrared images, placing limits on the motion of the central star cluster relative to Sgr A*, and measuring the proper mot…
