TL;DR: In this paper, the authors investigate the effect of line-of-sight temperature variations and noise on two commonly used methods to determine dust properties from dust-continuum observations of dense cores.

TL;DR: In this article, the authors apply radiative transfer calculations to these MC models in order to investigate the properties of CO line emission, including its relationship to the total, H2, and CO column densities, as well as the "X factor," the ratio of H2 column density to CO intensity.

TL;DR: In this article, the authors investigate how uncertainties in flux measurements affect the results from modified blackbody spectral energy distribution (SED) fits, and show that an inverse correlation between the dust temperature T and spectral index β naturally arises from least-squares fits due to the uncertainties, even for sources with a single T and β.

TL;DR: In this paper, the authors measured the mass and size of cloud fragments in several molecular clouds continuously over a wide range of spatial scales (0.05 − 0.15 - 0.34).

TL;DR: In this article, the formation of substructure in spiral galaxies using global MHD simulations, including gas self-gravity, was investigated, and it was shown that a sufficiently strong spiral potential is required to produce true spurs, consisting of interarm structures emerging from gas concentrations in the main spiral arms.
