Short timescale variation in the submillimeter flux of Sagittarius A*

Makoto Miyoshi, Yoshiaki Kato, Yoshiharu Asaki +8

We study short-timescale 340 GHz flux-density variability of Sgr A* using ALMA Cycle 3 observations. Careful self-calibration enabled 10 s snapshot imaging with very high effective…
