CO line emission represents the most accessible and widely used tracer of the molecular
ISM. This renders the translation of observed CO intensity into total H2 gas mass critical to …

We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

We present a uniform catalog of accurate distances to local molecular clouds informed by
the Gaia DR2 data release. Our methodology builds on that of Schlafly et al. First, we infer …

We present a three-dimensional map of interstellar dust reddening, covering three-quarters
of the sky out to a distance of several kiloparsecs, based on Pan-STARRS 1 (PS1) and …

In the past twenty years, the reconnaissance of 12CO and 13CO emission in the Milky Way
by single-dish millimeter-wave telescopes has expanded our view and understanding of …

This paper presents an all-sky model of dust emission from the Planck 353, 545, and 857
GHz, and IRAS 100 μm data. Using a modified blackbody fit to the data we present all-sky …

Context. Gaia data and stellar surveys open the way to the construction of detailed 3D maps
of the Galactic interstellar (IS) dust based on the synthesis of star distances and extinctions …

We review current understanding of star formation, outlining an overall theoretical framework
and the observations that motivate it. A conception of star formation has emerged in which …

We present∼ kiloparsec spatial resolution maps of the CO-to-H 2 conversion factor (α CO)
and dust-to-gas ratio (DGR) in 26 nearby, star-forming galaxies. We have simultaneously …

In this paper, we investigate the level of star formation activity within nearby molecular
clouds. We employ a uniform set of infrared extinction maps to provide accurate …
