Time Lag in Intra-Day Variability of Sgr A* between the Light Curves at 90 and 102GHz

Atsushi Miyazaki, Masato Tsuboi, Takahiro Tsutsumi

We performed the observation of the flux densities of SgrA* at 90 and 102GHz in order to detect the time lag between these frequencies using the Nobeyama Millimeter Array, which wa…
