We present a new model of interstellar dust in which large grains are a single composite
material," astrodust," and nanoparticle-sized grains come in distinct varieties including …

We present a self-consistent cross-calibration of the three main molecular gas mass tracers
in galaxies, namely the 12CO (1–0),[C i](3 P 1–3 P 0) lines, and the submm dust continuum …

A large fraction of interstellar carbon is locked up in solid grains. The nature, origin and
evolution of these grains have been investigated for decades. A combination of …

Dust is a ubiquitous feature of the cosmos, impinging directly or indirectly on most fields of
modern astronomy and astrophysics. Dust in the Galactic Environment, Second Edition …

Using physical models, we study the sensitivity of polycyclic aromatic hydrocarbon (PAH)
emission spectra to the character of the illuminating starlight, to the PAH size distribution …

We present a detailed overview of the science goals and predictions for the Prime-Cam
direct-detection camera–spectrometer being constructed by the CCAT-prime collaboration …

The dielectric function of interstellar dust material is modeled using observations of
extinction and polarization in the infrared, together with estimates for the mass of interstellar …

Magnetic fields (B) are an important factor controlling the star-formation process. The
leading method to observe B orientation is to use polarized thermal emission from aligned …

Abstract Investigating Protostellar Accretion (IPA) is a JWST Cycle 1 GO program that uses
NIRSpec integral field units and MIRI Medium Resolution Spectrograph to obtain 2.9–28 μm …

We report results from a Far Ultraviolet Spectrographic Explorer (FUSE) survey of interstellar
molecular hydrogen (H 2) in the Galactic disk toward 139 O-type and early B-type stars at …
