Detection of Sagittarius A* at 330 MHz with the Very Large Array

Abstract

We report the detection of Sagittarius A*, the radio source associated with our Galaxy's central massive black hole, at 330 MHz with the Very Large Array. Implications for the spectrum and emission processes of Sagittarius A* are discussed and several hypothetical geometries of the central region are considered.
