ATT12: The Antarctic 12-m Terahertz Telescope for Studies of Dusty Galaxies. I. Instrument Sensitivity and Science Forecasts
Koki Wakasugi, Takuya Hashimoto, Nario Kuno +13
We present a feasibility study of the Antarctic 12m Terahertz Telescope (ATT12), a next-generation facility to be constructed at New Dome Fuji in Antarctica, designed to open up th…
ALMA Fragmented Source Catalogue in Orion (FraSCO) I. Outflow interaction within an embedded cluster in OMC-2/FIR3, FIR4, and FIR5
Asako Sato, Satoko Takahashi, Shun Ishii +6
We present a high angular resolution () and wide-field () image of the 1.3-mm continuum, CO( = 2--1) line, and SiO( = 5--4) line emissions toward an…
CARMA-NRO Orion Survey: unbiased survey of dense cores and core mass functions in Orion A
Hideaki Takemura, Fumitaka Nakamura, Héctor G. Arce +15
The mass distribution of dense cores is a potential key to understand the process of star formation. Applying dendrogram analysis to the CARMA-NRO Orion CO (=1--0) data,…
Super-fast Rotation in the OMC 2/FIR 6b Jet
Yuko Matsushita, Satoko Takahashi, Shun Ishii +4
We present ALMA CO (=2--1) and 1.3 mm continuum observations of the high-velocity jet associated with the FIR 6b protostar located in the Orion Molecular Cloud-2. We detect a ve…
Atomic Carbon [CI] Mapping of the Nearby Galaxy M83
Yusuke Miyamoto, Atsushi Yasuda, Yoshimasa Watanabe +6
Atomic carbon (CI) has been proposed to be a global tracer of the molecular gas as a substitute for CO, however, its utility remains unproven. To evaluate the suitability of CI as…
The Core Mass Function in the Orion Nebula Cluster Region: What Determines the Final Stellar Masses?
Hideaki Takemura, Fumitaka Nakamura, Shuo Kong +29
Applying dendrogram analysis to the CARMA-NRO CO (=1--0) data having an angular resolution of 8", we identified 692 dense cores in the Orion Nebula Cluster (ONC) r…
The CO core mass function toward Orion A: Single-dish observations
Hideaki Takemura, Fumitaka Nakamura, Shun Ishii +6
We have performed an unbiased dense core survey toward the Orion A Giant Molecular Cloud in the CO (=1--0) emission line taken with the Nobeyama Radio Observatory (NRO) 4…
Nobeyama 45-m mapping observations toward nearby molecular clouds, Orion A, Aquila Rift, and M17: Project overview
Fumitaka Nakamura, Shun Ishii, Kazuhito Dobashi +16
We carried out mapping observations toward three nearby molecular clouds, Orion A, Aquila Rift, and M17, using a new 100 GHz receiver, FOREST, on the Nobeyama 45-m telescope. In th…
Nobeyama 45 m Mapping Observations toward Orion A. II. Classification of cloud structures and variation of the CO/CO abundance ratio due to far-UV Radiation
Shun Ishii, Fumitaka Nakamura, Yoshito Shimajiri +4
We present results of the classification of cloud structures toward the Orion A Giant Molecular Cloud based on wide-field CO ( = 1--0), CO ( = 1-0), and C$^{18}…
The CARMA-NRO Orion Survey: The filamentary structure as seen in CO emission
S. T. Suri, A. Sanchez-Monge, P. Schilke +18
We present an initial overview of the filamentary structure in the Orion A molecular cloud utilizing a high angular and velocity resolution CO(1-0) emission map that was rec…
Expanding CO Shells in the Orion A Molecular Cloud
Jesse R. Feddersen, Héctor G. Arce, Shuo Kong +6
We present the discovery of expanding spherical shells around low to intermediate-mass young stars in the Orion A giant molecular cloud using observations of CO (1-0) and $^…
