Nucleus of our Galaxy, the Milky Way.
Sagittarius A (Sgr A) at 1.3 x 2.5 arcsec resolution. An intensity-hue
representation: intensity is 6 cm continuum (B,
C, and D array 1983-1984) and color (hue) is spectral index between 6 and
20 cm. Blue is a non-thermal spectral
index of ~1 and red is an inverted spectrum of + 0. 5. The HII regions to
the east of Sgr A East are partially optically
thick with an inverted spectrum between 20 and 6 cm. The non-thermal source
Sgr A - East shows a shell structure
and may be a galactic supernova remnant with a size of about 10pc. The
thermal spiral in Sgr A - West has an
inverted spectrum which indicates a large electron density. Investigator(s): W.M. Goss, R.D. Ekers, J.H. van Gorkom, and U.J. Schwarz This image is available in the following downloadable versions:
