L- and M-band imaging observations of the Galactic Center region
T. Viehmann, A. Eckart, R. Schoedel +3
We present near-infrared H-, K-, L- and M-band photometry of the Galactic Center from images obtained at the ESO VLT in May and August 2002, using the NAOS/CONICA (H and K) and the…
Dust Embedded Sources at the Galactic Center. 2 to 4m imaging and spectroscopy in the central parsec
J. Moultaka, A. Eckart, T. Viehmann +4
We present the first L-band spectroscopic observations for a dozen stellar sources in the central 0.5 pc of the GC stellar cluster that are bright in the 2-4 micron wavelength doma…
Resolving the Host Galaxy of the Nearby QSO I Zw 1 with Sub-Arcsecond Multi-Transition Molecular Line Observations
J. G. Staguhn, E. Schinnerer, A. Eckart +1
We present the first sub-kpc 0.7" (~ 850 pc) resolution 12CO(1-0) molecular line observations of the ISM in the host galaxy of the QSO I Zw 1. The observations were obtained with t…
First Simultaneous NIR/X-ray Detection of a Flare from SgrA*
A. Eckart, F. K. Baganoff, M. Morris +9
We report on the first simultaneous near-infrared/X-ray detection of the Sgr A* counterpart which is associated with the massive black hole at the center of the Milky Way. The obse…
Weighing the cusp at the Galactic Centre
N. Mouawad, A. Eckart, S. Pfalzner +3
This paper has been withdrawn temporarily by the authors. As stars close to the galactic centre have short orbital periods it has been possible to trace large fractions of their or…
