Bias-free Measurement of Giant Molecular Cloud Properties
We review methods for measuring the sizes, line widths, and luminosities of giant molecular clouds (GMCs) in molecular-line data cubes with low resolution and sensitivity. We find that moment methods are robust and sensitive — making full use of both position and intensity information — and we recommend a standard method to measure the position angle, major and minor axis sizes, line width, and...
متن کاملGiant Molecular Clouds in M31 – I: Molecular Cloud Properties
We present Berkeley Illinois Maryland Association (BIMA) millimeter interferometer observations of giant molecular clouds (GMCs) along a spiral arm in M31. The observations consist of a survey using the compact configuration of the interferometer and follow-up, higher-resolution observations on a subset of the detections in the survey. The data are processed using an analysis algorithm designed...
متن کاملThe W51 Giant Molecular Cloud
We present 45-47 angular resolution maps at 50 sampling of the CO and CO J=1-0 emission toward a 1.39 × 1.33 region in the W51 H II region complex. These data permit the spatial and kinematic separation of several spectral features observed along the line of sight to W51, and establish the presence of a massive (1.2 × 10 M⊙), large (∆l × ∆b = 83pc × 114 pc) giant molecular cloud (GMC), defined ...
متن کاملMolecular clumps in the W51 giant molecular cloud
In this paper, we present a catalogue of dense molecular clumps located within the W51 giant molecular cloud (GMC). This work is based on Heterodyne Array Receiver Programme 13CO J = 3–2 observations of the W51 GMC and uses the automated CLUMPFIND algorithm to decompose the region into a total of 1575 clumps of which 1130 are associated with the W51 GMC. We clearly see the distinct structures o...
متن کاملPhysical properties of giant molecular clouds in the Large Magellanic Cloud
The Magellanic Mopra Assessment (MAGMA) is a high angular resolution 12CO (J = 1 → 0) mapping survey of giant molecular clouds (GMCs) in the Large Magellanic Cloud (LMC) and Small Magellanic Cloud using the Mopra Telescope. Here we report on the basic physical properties of 125 GMCs in the LMC that have been surveyed to date. The observed clouds exhibit scaling relations that are similar to tho...
