Sagittarius A West
Description
Radio continuum emission at 3.6 cm from the inner few parsecs of our Galaxy. The bright point source in the center is Sagittarius A*, which is likely a black hole at the center of the Galaxy. The mini-spiral of emission around the point source is from ionized gas that is in systematic motion about Sgr A*.
The 3.6 cm continuum emission from the center of the Galaxy observed in 1993 using VLA BnA configuration using all 27 antennas.
