Ammonia in infrared dark clouds [PDF]
Astronomy & Astrophysics, 2006 Context.While low mass clouds have been relatively well studied, our picture of high-mass star formation remains unclear. Infrared Dark Clouds appear to be the long sought population of cold and dense aggregations with the potential of harbouring the

A Semi-Automated Computational Approach for Infrared Dark Cloud Localization: A Catalog of Infrared Dark Clouds [PDF]
Publications of the Astronomical Society of the Pacific, 2023 The field of computer vision has greatly matured in the past decade, and many of the methods and techniques can be useful for astronomical applications.

Are infrared dark clouds really quiescent? [PDF]
Astronomy & Astrophysics, 2016 Context. The dense, cold regions where high-mass stars form are poorly characterized, 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 ...

Magnetic Fields in High-mass Infrared Dark Clouds [PDF]
The Astrophysical Journal, 2015 High-mass stars are cosmic engines known to dominate the energetics in the Milky Way and other galaxies. However, their formation is still not well understood.

Atomic carbon in an infrared dark cloud [PDF]
Proceedings of the International Astronomical Union, 2009 Infrared dark clouds (IRDCs) are potential sites of massive star formation, dark in the near-infrared, but in many cases already with indications of active star-formation from far-infrared and submm observations.

Spatial Variations of Dust Opacity and Grain Growth in Dark Clouds: L1689, L1709, and L1712
The Astrophysical JournalThe far-infrared (FIR) opacity of dust in dark clouds within the Ophiuchus molecular cloud is investigated through multiwavelength infrared observations from UKIDSS, Spitzer, and Herschel.

Infrared dark clouds on the far side of the Galaxy [PDF]
Astronomy & Astrophysics, 2015 Context. Infrared dark clouds are the coldest and densest portions of giant molecular clouds. The most massive ones represent some of the most likely birthplaces for the next generation of massive stars in the Milky Way.

A New Comprehensive Catalogue of Infrared Dark Clouds [PDF]
Proceedings of the International Astronomical Union, 2009 To better characterise infrared dark clouds (IRDCs), and the star formation within them, a comprehensive catalogue of IRDCs has been constructed from the Spitzer GLIMPSE and MIPSGAL archival data.

Radiative Transfer Simulations of Infrared Dark Clouds [PDF]
Proceedings of the International Astronomical Union, 2010 The determination of prestellar core structure is often based on observations of (sub)millimeter dust continuum. However, recently the Spitzer Space Telescope provided us with IR images of many objects not only in emission but also in absorption.
