H2 fluorescent emission from the diffuse interstellar medium

Astrophysics of Galaxies 2024-10-15 v1

Abstract

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 to sightlines where (1) the column densities of H and H2 have been measured and (2) the peak gas density can be estimated from extinction maps or observations of C2 absorption.
