ABSTRACT:
Images of Sgr A West at 8.7 micron , 12.5 micron , 20.8 micron and
24.5 micron were taken on 13 and 15 March
1998, and 15 June 1998 at the Keck 10m telescope with the mid-infrared camera MIRLIN.
MIRLIN uses a 128 X 128 Si:As BIB (hi-flux) detector with a scale
at Keck of 0.138 ''/pixel. The images are diffraction limited at
24.5 micron and near diffraction limited at 8.7 micron with the
seeing FWHM~0.15'' at 8.7 micron . The images will be presented
and a limit on the flux at the position of Sgr A* will be calculated
at all wavelengths. In addition, the images will be used to investigate
the color temperature and dust density distribution within the
field.
