J/ApJS/149/343      Giant molecular clouds in M33            (Engargiola+, 2003)

Giant molecular clouds in M33. I. BIMA all-disk survey. Engargiola G., Plambeck R.L., Rosolowsky E., Blitz L. <Astrophys. J. Suppl. Ser., 149, 343 (2003)> =2003ApJS..149..343E
ADC_Keywords: Molecular clouds ; Carbon monoxide ; H I data ; Radio lines Keywords: galaxies: individual (M33, NGC 598) - galaxies: ISM - ISM: clouds - ISM: molecules - radio lines: galaxies Abstract: We present the first interferometric 12CO (J=1->0) map of the entire Hα disk of M33. The 13" diameter synthesized beam corresponds to a linear resolution of 50pc, sufficient to distinguish individual giant molecular clouds (GMCs). From these data we generated a catalog of 148 GMCs with an expectation that no more than 15 of the sources are spurious. The catalog is complete down to GMC masses of 1.5x105M and contains a total mass of 2.3x107M. Description: Observations were made with the BIMA array in its most compact ("D") configuration at various times between 1999 August and 2000 October. File Summary:
