Broad-velocity-width Molecular Features in the Galactic Plane
Hiroki Yokozuka, Tomoharu Oka, Shunya Takekawa +2
We performed a systematic search for broad-velocity-width molecular features (BVFs) in the disk part of our Galaxy by using the CO J = 1-0 survey data obtained with the Nobeyama Ra…
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…
The Fifth Candidate for an Intermediate-mass Black Hole in the Galactic Center
Shunya Takekawa, Tomoharu Oka, Yuhei Iwata +2
We report the results of high-resolution molecular line observations of the high-velocity compact cloud HCN-0.085-0.094 with the Atacama Large Millimeter/submillimeter Array. The H…
An energetic high-velocity compact cloud: CO0.31+0.11
Shunya Takekawa, Tomoharu Oka, Sekito Tokuyama +5
We have discovered an energetic high-velocity compact cloud CO0.31+0.11 in the central molecular zone of our Galaxy. CO0.31+0.11 is located at a projected distance of $\sim 4…
Indication of Another Intermediate-mass Black Hole in the Galactic Center
Shunya Takekawa, Tomoharu Oka, Yuhei Iwata +2
We report the discovery of molecular gas streams orbiting around an invisible massive object in the central region of our Galaxy, based on the high-resolution molecular line observ…
Detection of Another Molecular Bubble in the Galactic Center
Shiho Tsujimoto, Tomoharu Oka, Shunya Takekawa +4
The region in the Galactic center has a high CO =3-2/=1-0 intensity ratio and extremely broad velocity width. This paper reports the detection of five expand…
