Resolving dense photodissociation regions: the structure of photochemical fronts in three-dimensional gas distributions

Brandt A. L. Gaches, Thomas G. Bisbas, Lothar Brendel +1

For decades, the Orion Bar has been the prototypical photodissociation region. Viewed nearly edge-on, it offers a unique window into the stratified chemical structure of the atomic…

A HINSA view of cosmic-ray ionization in IC 348 and NGC 1333: evidence for a strong low-energy cosmic-ray disparity

Gan Luo, Marco Padovani, Daniele Galli +5

The cosmic-ray ionization rate (CRIR) is one of the fundamental parameters influencing the chemical and dynamical evolution of molecular clouds. Although observations in recent yea…

The Colors of Ices: Measuring ice column density through photometry

Adam Ginsburg, Savannah R. Gramze, Matthew L. N. Ashby +8

Ices imprint strong absorption features in the near- and mid-infrared, but until recently they have been studied almost exclusively with spectroscopy toward small samples of bright…

Complex organic molecules and cosmic ray ionisation rate towards the massive protostar Cepheus A HW2

Emma W. Nielsen, Anna Punanova, Eva Wirström +5

Cosmic rays (CRs) are important drivers for molecular chemistry in star-forming regions, and laboratory experiments have shown that CRs can stimulate the release of complex organic…

Mapping CO Ice in a Star-Forming Filament in the 3 kpc Arm with JWST

Savannah Gramze, Adam Ginsburg, Nazar Budaiev +14

CO gas emission is a fundamental tool for measuring column density, but in cold, dark clouds, much of the CO is locked away in ice. We present JWST results from observations of a s…

The impact of attenuation on cosmic-ray chemistry: I. Abundances and chemical calibrators in molecular clouds

Arghyadeb Roy, Brandt A. L. Gaches, Jonathan C. Tan

The chemistry of shielded molecular gas is primarily driven by energetic, charged particles dubbed cosmic rays (CRs), in particular those with energies under 1 GeV. CRs ionize mole…
