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.

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 2004BASI...32..335G)
G = Object associated with TeV gamma-ray source
(e.g., Aharonian et al., 2008A&A...481..401A 2008A&A...481..401A)
X = Object associated with {X-ray} source
