M-BAND SPECTRA OF DUST-EMBEDDED SOURCES AT THE GALACTIC CENTER

Dusty Sources at the Galactic Center: The N- and Q-band view with VISIR

We present mid-infrared N and Q-band photometry of the Galactic Center from images obtained with the mid-infrared camera VISIR at the ESO VLT in May 2004. The high resolution and sensitivity possible with VISIR enables us to investigate a total of over 60 point-like sources, an unprecedented number for the Galactic Center at these wavelengths. Combining these data with previous results at short...

The infrared L ’ - band view of the Galactic Center with NAOS - CONICA at VLT ⋆

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 the black hole, that could sign the first thermal infrared detection of Sgr A*. A multi-wavelength maximum likelihood analysis has allowed us to eliminate all but two of the candidates for gravitational lensing propos...

The Galactic Center : An Interacting System of Unusual Sources

A CATALOG OF 24μm SOURCES TOWARD THE GALACTIC CENTER

We present a ∼ 1.5 × 8 (220×1195pc) Multiband Imaging Photometer for Spitzer 24μm image of the Galactic Center and an accompanying point source list. This image is the highest spatial resolution (6 ∼ 0.25pc) and sensitivity map ever taken across the GC at this wavelength, showing the emission by warm dust in unprecedented detail. Over 120,000 point sources are identified in this catalog with si...

The galactic center: An interacting system of unusual sources

The region bounded by the inner tens of light-years at the center of the Milky Way Galaxy contains five principal components that coexist within the central deep well of gravitational potential. These constituents are a black hole candidate (Sgr A*) with a mass equivalent to 2.6 +/- 0.2 x 10(6) solar masses, a surrounding cluster of evolved stars, a complex of young stars, molecular and ionized...
