J/PASJ/62/557  CO clouds in the Galactic Center from NANTEN  (Takeuchi+, 2010)

NANTEN survey of molecular clouds toward the Galactic Center. Association of compact astronomical objects. Takeuchi T., Yamamoto H., Torii K., Kudo N., Hayakawa T., Kawamura A., Mizuno N., Onishi T., Mizuno A., Ogawa H., Fukui Y. <Publ. Astron. Soc. Jap., 62, 557-612 (2010)> =2010PASJ...62..557T
ADC_Keywords: Molecular clouds ; Radio lines ; Carbon monoxide Keywords: ISM: clouds - ISM: HII regions - ISM: supernova remnants Abstract: In order to better understand molecular clouds and their properties toward the Galactic center region, we have analyzed the NANTEN database of 12CO (J=1-0) and 13CO (J=1-0) to search for associations with candidates for young high-mass star-forming regions, such as IRAS point sources, radio continuum sources, recombination line sources, maser line sources, and other molecular line sources. We have also compared the data with TeV gamma-ray sources. The analyzed region covers -12°≤l≤12° and -1.5°≤b≤1.5° for 12CO, and -6°≤l≤8° and -1°≤b≤1° for 13CO. As a result, we identified 167 IRAS point sources, 73 recombination line sources, 58 maser sources, 107 radio continuum sources, and 77 molecular line sources associated with 169 positions with the CO emission. Description: We used the NANTEN 12CO(J=1-0) Galactic Plane Survey dataset Mizuno & Fukui (2004, ASP Conf. Ser., 317, 59) in the present analysis. The observations were carried out with NANTEN, a millimeter-wave telescope of Nagoya University, located at Las Campanas Observatory in Chile. File Summary:

Note (1): We classified molecular clouds according to the following criteria: a = molecular clouds associated with objects having velocity information whose detection lies within 5km/s of CO peak velocity b = molecular clouds with associated objects whose velocity is separated by more than 5km/s from CO peak velocity c = molecular clouds with associated objects that are coincident in position only without velocity information. Note (2): Notes as follows: S = SNRs are from the Green SNR catalog (Green, 2004BASI...32..335G) G = Object associated with TeV gamma-ray source (e.g., Aharonian et al., 2008A&A...481..401A) X = Object associated with {X-ray} source
