Are infrared dark clouds really quiescent? [PDF]
Astronomy & Astrophysics, 2016 The dense, cold regions where high-mass stars form are poorly characterised, yet they represent an ideal opportunity to learn more about the initial conditions of high-mass star formation (HMSF), since high-mass starless cores (HMSCs) lack the violent feedback seen at later evolutionary stages.

THE GIANT MOLECULAR CLOUD ENVIRONMENTS OF INFRARED DARK CLOUDS [PDF]
The Astrophysical Journal, 2015 We study Giant Molecular Cloud (GMC) environments surrounding 10 Infrared Dark Clouds (IRDCs), using $^{13}$CO(1-0) emission from the Galactic Ring Survey. We measure physical properties of these IRDCs/GMCs on a range of scales extending to radii, R, of 30 pc.

THE DYNAMICAL STATE OF FILAMENTARY INFRARED DARK CLOUDS [PDF]
The Astrophysical Journal, 2011 The dense, cold gas of Infrared Dark Clouds (IRDCs) is thought to be representative of the initial conditions of massive star and star cluster formation. We analyze 13CO(J=1-0) line emission data from the Galactic Ring Survey of Jackson et al. for two filamentary IRDCs, comparing the mass surface densities derived from 13CO, Sigma_13CO, with those ...

15N fractionation in infrared-dark cloud cores [PDF]
Astronomy & Astrophysics, 2017 Nitrogen is one of the most abundant elements in the Universe and its 14N/15N isotopic ratio has the potential to provide information about the initial environment in which our Sun formed. Recent findings suggest that the Solar System may have formed in a massive cluster since the presence of short-lived radioisotopes in meteorites can only be ...

The modelling of infrared dark cloud cores [PDF]
Astronomy & Astrophysics, 2005 This paper presents results from modelling 450 mu m and 850 mu m continuum and HCO+ line observations of three distinct cores of an infrared dark cloud (IRDC) directed toward the W51 GMC. In the sub-mm continuum these cores appear as bright, isolated emission features.

Combining visible and infrared radiometry and lidar data to test simulations in clear and ice cloud conditions [PDF]
, 2010 Measurements taken during the 2003 Pacific THORPEX Observing System Test (P-TOST) by the MODIS Airborne Simulator (MAS), the Scanning High-resolution Interferometer Sounder (S-HIS) and the Cloud Physics Lidar (CPL) are compared to simulations performed ...
