A Face-on Accretion Disk Geometry Revealed by Millimeter-wave Periodicity in Sgr A∗
We analyzed 77 epochs of Atacama Large Millimeter/submillimeter Array archival data to investigate flux variability in Sagittarius A ^∗ , the supermassive black hole at the Galactic center. Among these, we identified a rare but unusually clear and coherent ∼52 minute sinusoidal modulation at 230 GHz...
