Parabolic-like Trend in SiO Ratios throughout the Central Molecular Zone: Possible Signature of a Past Nuclear Activity in the Galactic Center
Shunya Takekawa, Tomoharu Oka, Shiho Tsujimoto +5
We report the discovery of a characteristic trend in the intensity ratios of SiO emissions across the Central Molecular Zone (CMZ) of our Galaxy. Using the Nobeyama Radio Observato…

Millimeter-wave CO and SiO Observations toward the Broad-velocity-width Molecular Feature CO 16.134-0.553: a Smith cloud scenario?
Hiroki Yokozuka, Tomoharu Oka, Shiho Tsujimoto +2
We report the results of the CO =1-0 and SiO =2-1 mapping observations towards the broad-velocity-width molecular feature CO 16.134-0.553 with the Nobeyama Ra…

Discovery of the Tadpole Molecular Cloud near the Galactic Nucleus
Miyuki Kaneko, Tomoharu Oka, Hiroki Yokozuka +4
In this paper, we report the discovery of an isolated, peculiar compact cloud with a steep velocity gradient at $2\farcm 6$ northwest of Sgr A*. This ``Tadpole'' molecular cloud is…
