![]() ![]() Spectrum that peaks at submillimeter wavelengths have similar inner accretion Relationship further suggests that a group of radio sources with a broadband With the emission originating from the event horizon. This discovery suggests the sub-mm emission is optically thin Combined with previous studies, we show aĬorrelation between the the timescale and the black hole mass over three orders Theĭetected timescales are comparable to the orbital timescale at the event We detect a timescale for all the sources except NGC 4552. Variability is saturated by modeling these sources' light curve as a damped We measure the characteristic timescale at which the Years of observations using Submillimeter Array for Centaurus A, NGC 4374, NGCĤ278, and NGC 5077 and one year of observations for NGC 4552 and NGC 4579.
