High resolutions maps of the galactic center at 2.2 and 10 μ

Abstract

Photometric maps of the central 1' of the Galactic center are presented at 2.2 and 10μ with a spatial resolution of ≈ 2'.'5. Most of the 2.2-μ radiation within the central 2 pc comes from discrete sources with absolute 2.2-μ magnitudes brighter than -8. At 10μ, nine discrete sources plus an extended ridge of emission are seen. Five of the discrete sources are located within the extended ridge and have properties similar to the planetary nebula NGC 7027.
