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…
Catalog of High Velocity Dispersion Compact Clouds in the Central Molecular Zone of Our Galaxy
Tomoharu Oka, Asaka Uruno, Rei Enokiya +5
This study developed an automated identification procedure for compact clouds with broad velocity widths in the spectral line data cubes of highly crowded regions. The procedure wa…
A Global Analysis of Resonance-enhanced Light Scalar Dark Matter
Tobias Binder, Sreemanti Chakraborti, Shigeki Matsumoto +1
We study a minimal model for a light scalar dark matter, requiring a light scalar mediator to address the core-cusp problem and interact with the standard model particles. We analy…
New Look at the Molecular Superbubble Candidate in the Galactic Center
Shiho Tsujimoto, Tomoharu Oka, Shunya Takekawa +10
The region in the Galactic center is characterized by multiple shell-like structures and their extremely broad velocity widths. We revisit the molecular supe…
Systematic Variations of CO J=2-1/1-0 Ratio in The Barred Spiral Galaxy M83
J. Koda, T. Sawada, K. Sakamoto +18
We present spatial variations of the CO J=2-1/1-0 line ratio in M83 using Total Power array data from ALMA. While the intensities of these two lines correlate tightly, the ratio va…
