Remarkable flares from the galactic center

Sagittarius A* (Sgr A*), the supermassive black hole at the center of our Milky Way Galaxy, is 100 times closer to us than any other SMBH and therefore a prime candidate for studies of how matter radiates as it accretes onto black holes. SgrA* has been observed for decades and rapid fluctuations reported from X-ray to the near infrared wavelengths (intervening dust reduces optical light signals by a factor of over a trillion) and at submillimeter and radio wavelengths. Modeling the mechanisms of...
