Molecular clouds in the center of M 81 [PDF]
Astronomy & Astrophysics, 2007 We investigate the molecular gas content and the excitation and fragmentation properties in the central region of the spiral galaxy Messier 81 in both the ^{12}CO(1-0) and ^{12}CO(2-1) transitions. We have recently observed the two transitions of CO in the M~81 center with A, B, and HERA receivers of the IRAM 30-m telescope.

The Earliest Phases of Star Formation (EPoS): a Herschel key project - The thermal structure of low-mass molecular cloud cores [PDF]
, 2013 Context. The temperature and density structure of molecular cloud cores are the most important physical quantities that determine the course of the protostellar collapse and the properties of the stars they form. Nevertheless, density profiles often rely

QUANTIFYING OBSERVATIONAL PROJECTION EFFECTS USING MOLECULAR CLOUD SIMULATIONS [PDF]
, 2013 The physical properties of molecular clouds are often measured using spectral-line observations, which provide the only probes of the clouds' velocity structure.

Giant Molecular Clouds in M31. I. Molecular Cloud Properties [PDF]
The Astrophysical Journal, 2007 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.

Large scale IRAM 30 m CO-observations in the giant molecular cloud complex W43 [PDF]
, 2013 We aim to give a full description of the distribution and location of dense molecular clouds in the giant molecular cloud complex W43. It has previously been identified as one of the most massive star-forming regions in our Galaxy.

The energetics of molecular clouds. II - The S140 molecular cloud
The Astrophysical Journal, 1978 Techniques of analysis which allow estimates of kinetic temperature, gas density, gas cooling rate, and dust cooling rate are applied to the S140 molecular cloud. Maps of this cloud in various molecular lines are examined which reveal the existence of a strong temperature and density peak near the H-alpha rim and the presence of a strong near-IR source

Insights on molecular cloud structure [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractStars form in the densest regions of clouds of cold molecular hydrogen. Measuring structure in these clouds is far from trivial as 99% of the mass of a molecular cloud is inaccessible to direct observation. Over the last decade we have been developing an alternative, more robust density tracer technique based on dust extinction measurements ...
