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…
ALMA Astrometry of the Objects within 0.5 pc of Sagittarius A
Masato Tsuboi, Takahiro Tsutsumi, Atsushi Miyazaki +2
Atacama Large Millimeter/Submillimeter Array (ALMA) is promising to be a powerful tool for precision astrometry of the area around Sagittarius A (Sgr A) because it ha…
Hot Molecular Core Candidates in the Galactic Center 50 km/s Molecular Cloud
Ryosuke Miyawaki, Masato Tsuboi, Kenta Uehara +1
We present the results based on the 2.5 arcsec-resolution observations using Atacama Large Millimeter/submillimeter Array (ALMA) of the Galactic Center Molecular Cloud G-0.02-0.07,…
Instability analysis for spiral arms of local galaxies: M51, NGC3627 and NGC628
Shigeki Inoue, Toshinobu Takagi, Atsushi Miyazaki +3
We investigate dynamical states of grand-design spiral arms in three local galaxies: M51, NGC3627 and NGC628. Based on linear perturbation analysis considering multiple components…
Cloud-Cloud Collision in the Galactic Center Arc
Masato Tsuboi, Yoshimi Kitamura, Kenta Uehara +4
We performed a search of cloud-cloud collision (CCC) sites in the Sagittarius A molecular cloud (SgrAMC) based on the survey observations using the Nobeyama 45-m telescope in the C…
Where is the Western Part of the Galactic Center Lobe Located really?
Masato Tsuboi, Takahiro Tsutsumi, Yoshimi Kitamura +3
The Galactic Center Lobe (GCL) is a peculiar object widely protruding from the Galactic plane toward the positive Galactic latitude, which had been found toward the Galactic Center…
