The "True" Column Density Distribution in Star-Forming Molecular Clouds
(American Astronomical Society, 2009)
We use the COMPLETE Survey's observations of the Perseus star-forming region to assess and intercompare the three methods used for measuring column density in molecular clouds: near-infrared (NIR) extinction mapping; thermal ...
The Perils of Clumpfind: The Mass Spectrum of Substructures in Molecular Clouds
(American Astronomical Society, 2009)
We study the mass spectrum of substructures in the Perseus Molecular Cloud Complex traced by \(^{13}CO(1–0)\), finding that \(dN/dM \ \alpha \ M^{−2.4}\) for the standard Clumpfind parameters. This result does not agree ...
Dense Cores in Perseus: The Influence of Stellar Content and Cluster Environment
(American Astronomical Society, 2009)
We present the chemistry, temperature, and dynamical state of a sample of 193 dense cores or core candidates in the Perseus Molecular cloud and compare the properties of cores associated with young stars and clusters with ...
