The cloud-scale density, velocity dispersion, and gravitational boundedness of the interstellar medium (ISM) vary within and among galaxies. In turbulent models, these properties play key roles in the ability of gas to ...

We explore the use of mm-wave emission line ratios to trace molecular gas density when observations integrate over a wide range of volume densities within a single telescope beam. For observations targeting external galaxies, ...

We present a detailed analysis of the morphological properties of the Crab Nebula across the electromagnetic spectrum based on new and previous high-quality data from radio to X-rays. In the radio range we obtained an image ...

We present a multiwavelength study of two Herbig-Haro (HH) objects (137 and 138) that may be associated. We use Gemini H-2 (2.12 mu m) and K (2.2 mu m) images, as well as Atacama Pathfinder EXperiment molecular line ...
