Two Distinct Objects in the Galactic Center: The Supermassive
Black Hole and a Population of Synchrotron Filaments
Observations over the past two decades have established that Sagittarius A* (Sgr A*), a 4.3 million solar mass black hole, resides at the Galactic center, consistent with general relativity. Its variable emission, including infrared and X-ray flares, probes accretion processes within a few Schwarzschild radii. I will present recent multi-wavelength results and discuss a unified framework for the flaring emission across infrared, X-ray, and radio bands. I will further examine the possible connection between past activity of Sgr A* and the origin of the synchrotron filaments in the Galactic center, emphasizing scenarios in which they arise from relativistic particles and magnetic fields powered by past activity of Sgr A*
