In this study, a novel type of Fourier transform radio spectrometer (termed as all-digital radio spectrometer; ADRS) has been developed in which all functionalities comprising a ra…
Current status and future plan of Osaka Prefecture University 1.85-m mm-submm telescope project
Atsushi Nishimura, Kazuki Tokuda, Ryohei Harada +25
We report the current status of the 1.85-m mm-submm telescope installed at the Nobeyama Radio Observatory (altitude 1400 m) and the future plan. The scientific goal is to reveal th…
OH 18 cm Transition as a Thermometer for Molecular Clouds
Yuji Ebisawa, Hiroshi Inokuma, Nami Sakai +3
We have observed the four hyperfine components of the 18 cm OH transition toward the translucent cloud eastward of Heiles Cloud 2 (HCL2E), the cold dark cloud L134N, and the photod…
Large-scale CO (J=4-3) Mapping toward the Orion-A Giant Molecular Cloud
Shun Ishii, Masumichi Seta, Makoto Nagai +10
We have mapped the Orion-A Giant Molecular Cloud in the CO (J=4-3) line with the Tsukuba 30-cm submillimeter telescope.The map covered a 7.125 deg^2 area with a 9' resolution, incl…
Revealing the physical properties of molecular gas in Orion with a large scale survey in J=2-1 lines of 12CO, 13CO and C18O
Atsushi Nishimura, Kazuki Tokuda, Kimihiro Kimura +8
We present fully sampled ~3' resolution images of the 12CO(J=2-1), 13CO(J=2-1), and C18O(J=2-1) emission taken with the newly developed 1.85-m mm-submm telescope toward the entire…
Cluster Formation Triggered by Filament Collisions in Serpens South
Fumitaka Nakamura, Koji Sugitani, Tomohiro Tanaka +24
The Serpens South infrared dark cloud consists of several filamentary ridges, some of which fragment into dense clumps. On the basis of CCS (), HCN (), N$_2…
The jet and arc molecular clouds toward Westerlund 2, RCW 49, and HESS J1023-575; 12CO and 13CO (J=2-1 and J=1-0) observations with NANTEN2 and Mopra Telescope
N. Furukawa, A. Ohama, T. Fukuda +20
We have made new CO observations of two molecular clouds, which we call "jet" and "arc" clouds, toward the stellar cluster Westerlund 2 and the TeV gamma-ray source HESS J1023-575.…
Molecular Clouds Toward the Super Star Cluster NGC3603; Possible Evidence for a Cloud-Cloud Collision in Triggering the Cluster Formation
