J/ApJ/661/830           Giant molecular clouds of M33        (Rosolowsky+, 2007)

High-resolution molecular gas maps of M33. Rosolowsky E., Keto E., Matsushita S., Willner S.P. <Astrophys. J., 661, 830-844 (2007)> =2007ApJ...661..830R
ADC_Keywords: Galaxies, nearby ; Molecular clouds ; Radio lines Keywords: catalogs - galaxies: individual (M33) - ISM: clouds - radio lines: ISM Abstract: New observations of CO (J=1->0) line emission from M33, using the 25 element BEARS focal plane array at the Nobeyama Radio Observatory 45m telescope, in conjunction with existing maps from the BIMA interferometer and the FCRAO 14m telescope, give the highest resolution (13") and most sensitive (σrms∼60mK) maps to date of the distribution of molecular gas in the central 5.5kpc of the galaxy. A new catalog of giant molecular clouds (GMCs) has a completeness limit of 1.3x105M. Description: The BEARS array on the 45m telescope at NRO consists of 25 SIS mixer receivers arranged in a 5x5 array with 41.1" between the elements. We observed from 2005 February 9 to 17.
