A Transient Radio Source near the Center of the Milky Way Galaxy (original) (raw)

In late December 1990, a new radio source appeared near the center of the Milky Way, identified as the Galactic Center Transient (GCT). This source, which exhibits significant radio variability, is distinguished by a flux density that rivals that of Sagittarius A (Sgr A), the well-known compact radio source at the Galactic center. Analysis suggests that the GCT is associated with an X-ray binary system and is likely embedded within or located behind a molecular cloud. The paper discusses the implications of these findings in the context of the extreme nature of the Galactic center and the relationships among various observed structures in this region.
