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…

Nuclear Stellar Disk-like Nature in the Kinematics of SiO Maser Stars around Sagittarius A*
Masato Tsuboi, Takahiro Tsutsumi, Ryosuke Miyawaki +1
We present a detailed analysis of the kinematics of SiO maser stars around the center of the Milky Way, Sagittarius A* (Sgr A*). We used the archive data in the SiO v=1, J=2-1 emis…
