Mapping the Cosmic-Ray Ionization Rate in the Local Galaxy with H
Nick Indriolo, Alexei V. Ivlev, T. Pellegrin +6
Chemistry in diffuse molecular clouds relies primarily on rapid ion-molecule reactions. Formation of the initial ions, H and H, is dominated by cosmic-ray ionization of H…

H2 fluorescent emission from the diffuse interstellar medium
David A. Neufeld
A simple analytic model is presented to predict the near-IR H2 fluorescent line intensities emitted by diffuse interstellar clouds with a Plummer density profile. It is applicable…

JWST-IPA: Chemical Inventory and Spatial Mapping of Ices in the Protostar HOPS370 -- Evidence for an Opacity Hole and Thermal Processing of Ices
Himanshu Tyagi, Manoj P., Mayank Narang +35
The composition of protoplanetary disks, and hence the initial conditions of planet formation, may be strongly influenced by the infall and thermal processing of material during th…
