J/PASJ/57/917  CO molecular clouds in southern Galactic Warp (Nakagawa+, 2005)

An unbiased search for molecular clouds in the southern Galactic Warp. Nakagawa M., Onishi T., Mizuno A., Fukui Y. <Publ. Astron. Soc. Jap., 57, 917-931 (2005)> =2005PASJ...57..917N
ADC_Keywords: Molecular clouds ; Radio lines Keywords: Galaxy: warp - ISM: abundances - ISM: clouds - radio lines: ISM Abstract: We made an unbiased search for molecular clouds in the Galactic Warp. This survey, covering an area of 56 square degrees at l=252° to 266° and b=-5° to -1°, revealed 70 molecular clouds, while only 6 clouds were previously known in this sector at R≳14.5kpc. Description: Observations were made in the J=1-012CO emission line at 2.6mm wavelength with the NANTEN telescope at the Las Campanas Observatory in Chile in the period from 2001 July to 2002 August.

Note (1): Distance from the galactic center for b=0, assuming flat rotation curve (R=8.5kpc, V=220km/s). Note (2): Comments are as follows: cold IRAS = clouds which have a cold IRAS point source near the peak double peak = clouds which have multiple velocity components in a single beam and neither of them is well-resolved not complete = For the last cloud, No. 71 (no data)
