Map of the Interstellar Continuum FUV Field within 800 Parsecs

David Lomeli, Kedron Silsbee, Alexei Ivlev +1

The far-ultraviolet (FUV) field, consisting of photons with energies between 6 and 13.6 electron volts, plays an important role in the chemical and thermodynamical evolution of the…

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…

The Snake Filament: A study of polarization and kinematics

Farideh S. Tabatabaei, Elena Redaelli, Gabriel A. P. Franco +2

The role of magnetic fields in the formation of dense filamentary structures in molecular clouds is critical for understanding the star formation process. The Snake filament in or…

The densities in diffuse and translucent molecular clouds: estimates from observations of C and from 3-dimensional extinction maps

David A. Neufeld, Daniel E. Welty, Alexei V. Ivlev +7

Newly-computed collisional rate coefficients for the excitation of C in collisions with H, presented recently by Najar and Kalugina (2020), are significantly larger than th…

Re-evaluation of the cosmic-ray ionization rate in diffuse clouds

M. Obolentseva, A. V. Ivlev, K. Silsbee +6

All current estimates of the cosmic-ray (CR) ionization rate rely on assessments of the gas density along the probed sight lines. Until now, these have been based on observations o…
