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 …

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 …

Context. In the past few years, there has been a rise in the detection of streamers,
asymmetric flows of material directed toward the protostellar disk with material from outside …

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 …

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 …

Context. Gas phase Elemental abundances in molecular CloudS (GEMS) is an IRAM 30-m
Large Program aimed at determining the elemental abundances of carbon (C), oxygen (O) …

We estimate the conversion factor relating CO emission to H 2 mass, α CO, in five Local
Group galaxies that span approximately an order of magnitude in metallicity—M 31, M 33 …

Context. Density and velocity fluctuations on virtually all scales observed with modern
telescopes show that molecular clouds (MCs) are turbulent. The forcing and structural …

To date, about two dozen low-mass embedded protostars exhibit rich spectra with lines of
complex organic molecules (COMs). These protostars seem to possess a different …

The properties of Galactic molecular clouds tabulated by Solomon et al.(SRBY) are re-
examined using the Boston University-FCRAO Galactic Ring Survey of 13 CO J= 1–0 …
