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 …

An examination of the uses of data within a changing knowledge infrastructure, offering
analysis and case studies from the sciences, social sciences, and humanities.“Big Data” is …

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 …

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 …

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

Feedback from massive stars is believed to play a critical role in shaping the galaxy mass
function, the structure of the interstellar medium (ISM) and the low efficiency of star …

Synthetic observations are playing an increasingly important role across astrophysics, both
for interpreting real observations and also for making meaningful predictions from models. In …

We leverage the 1 pc spatial resolution of the Leike et al. three-dimensional (3D) dust map
to characterize the 3D structure of nearby molecular clouds (d≲ 400 pc). We start by" …

Star formation is slow in the sense that the gas consumption time is much longer than the
dynamical time. It is also inefficient; star formation in local galaxies takes place in giant …

Star formation is such a complex process that accurate numerical tools are needed to
quantitatively examine the mass distribution and accretion of fragments in collapsing …
