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…
Tidally-disrupted Molecular Clouds falling to the Galactic Center
Masato Tsuboi, Yoshimi Kitamura, Kenta Uehara +2
We found a molecular cloud connecting from the outer region to the "Galactic Center Mini-spiral (GCMS)" which is a bundle of the ionized gas streams adjacent to Sgr A*. The molecul…
A Measurement of Proper Motions of SiO Maser Sources in the Galactic Center with the VLBA
T. Oyama, M. Miyoshi, S. Deguchi +2
We report on the high-precision astrometric observations of maser sources around the Galactic Center in the SiO J=1--0 v=1 and 2 lines with the VLBA during 2001 -- 2004. With phase…
Water maser motions in W3(OH) and a determination of its distance
K. Hachisuka, A. Brunthaler, K. M. Menten +6
We report phase-referencing VLBA observations of H2O masers near the star-forming region W3(OH) to measure their parallax and absolute proper motions. The measured annual parallax…
J-Net Galactic Plane Survey of VLBI Radio Sources for VLBI Exploration of Radio Astrometry (VERA)
M. Honma
In order to search for new VLBI sources in the Galactic plane that can be used as phase reference sources in differential VLBI, we have conducted 22 GHz observations of radio sourc…
