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 cosmological parameter results from the final full-mission Planck measurements
of the cosmic microwave background (CMB) anisotropies, combining information from the …

This study presents a catalog of 8107 molecular clouds that covers the entire Galactic plane
and includes 98% of the 12 CO emission observed within $ b\pm 5^\circ $. The catalog was …

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 …

Recent studies of the nearest star-forming clouds of the Galaxy at submillimeter wavelengths
with the Herschel Space Observatory have provided us with unprecedented images of the …

We present first results from the Herschel Gould Belt survey for the B211/L1495 region in the
Taurus molecular cloud. Thanks to their high sensitivity and dynamic range, the Herschel …

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 …

Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

The mass of molecular gas in an interstellar cloud is often measured using line emission
from low rotational levels of CO, which are sensitive to the CO mass, and then scaling to the …
