Giant Molecular Clouds in the Local Group Galaxy M33
P. Gratier, J. Braine, N. J. Rodriguez-Fernandez +7
We present an analysis of the systematic CO(2-1) survey at 12" resolution covering most of the local group spiral M 33 which, at a distance of 840 kpc, is close enough that individ…
A Molecular Star Formation Law in the Atomic Gas Dominated Regime in Nearby Galaxies
Andreas Schruba, Adam K. Leroy, Fabian Walter +11
We use the IRAM HERACLES survey to study CO emission from 33 nearby spiral galaxies down to very low intensities. Using atomic hydrogen (HI) data, mostly from THINGS, we predict th…
COLD GASS, an IRAM Legacy Survey of Molecular Gas in Massive Galaxies: II. The non-universality of the Molecular Gas Depletion Timescale
Amelie Saintonge, Guinevere Kauffmann, Jing Wang +21
We study the relation between molecular gas and star formation in a volume-limited sample of 222 galaxies from the COLD GASS survey, with measurements of the CO(1-0) line from the…
COLD GASS, an IRAM legacy survey of molecular gas in massive galaxies: I. Relations between H2, HI, stellar content and structural properties
Amelie Saintonge, Guinevere Kauffmann, Carsten Kramer +21
We are conducting COLD GASS, a legacy survey for molecular gas in nearby galaxies. Using the IRAM 30m telescope, we measure the CO(1-0) line in a sample of ~350 nearby (D=100-200 M…
High resolution imaging of the GG Tau system at 267 GHz
Vincent Piétu, Frédéric Gueth, Pierre Hily-Blant +2
Studying circumbinary disks is critical to understanding the formation mechanisms of binary stars. While optical or mid-infrared images reveal the scattered mission, millimeter obs…
A Constant Molecular Gas Depletion Time in Nearby Disk Galaxies
F. Bigiel, A. K. Leroy, F. Walter +8
We combine new sensitive, wide-field CO data from the HERACLES survey with ultraviolet and infrared data from GALEX and Spitzer to compare the surface densities of H2, Sigma_H2, an…
