The Nobeyama 45 m Survey of Shocked Molecular Gas in the Central Molecular Zone. I. Survey Data, Cloud Catalog, and SiO Line-Ratio Trends
Shunya Takekawa, Shiho Tsujimoto, Tomoharu Oka +1
We present large-scale molecular line maps of the Central Molecular Zone (CMZ) in our Galaxy obtained with the Nobeyama Radio Observatory 45 m telescope. The observations cover a 3…
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…
A broad linewidth, compact, millimeter-bright molecular emission line source near the Galactic Center
Adam Ginsburg, John Bally, Ashley T. Barnes +37
A compact source, G0.02467-0.0727, was detected in ALMA \threemm observations in continuum and very broad line emission. The continuum emission has a spectral index ,…
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…
ALMA View of the High-velocity-dispersion Compact Cloud CO 0.02-0.02 at the Galactic Center
Yuhei Iwata, Tomoharu Oka, Shunya Takekawa +2
We report the results of observations toward the center of the molecular cloud CO 0.02-0.02 made using the Atacama Large Millimeter/Submillimeter Array. The successfully obtained 1…
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…
