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 …

The cold interstellar medium (ISM) plays a central role in the galaxy evolution process. It is
the reservoir that fuels galaxy growth via star formation, the repository of material formed by …

Context. Measurement of the Galactic neutral atomic hydrogen (H i) column density, NH i,
and brightness temperatures, TB, is of high scientific value for a broad range of astrophysical …

density, NH i, and brightness temperatures, TB, is of high scientific value for a broad range of …

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 …

We measure the velocity dispersion, σ, and surface density, Σ, of the molecular gas in
nearby galaxies from CO spectral line cubes with spatial resolution 45–120 pc, matched to …

We present a new, open source, free, semi-analytic model (SAM) of galaxy formation, Shark,
designed to be highly flexible and modular, allowing easy exploration of different physical …

We present a theoretical framework in which bound stellar clusters arise naturally at the high-
density end of the hierarchy of the interstellar medium (ISM). Due to short free-fall times …

We investigate the relation between star formation rate (SFR) and gas surface densities in
Galactic star-forming regions using a sample of young stellar objects (YSOs) and massive …

ABSTRACT Spitzer Space Telescope and Herschel Space Observatory imaging of M31 is
used, with a physical dust model, to construct maps of dust surface density, dust-to-gas ratio …
