Ubiquitous argonium (ArH+) in the diffuse interstellar medium: A molecular tracer of almost purely atomic gas [PDF]
Astronomy & Astrophysics, 2014 We describe the assignment of a previously unidentified interstellar absorption line to ArH$^+$ and discuss its relevance in the context of hydride absorption in diffuse gas with a low H$_2$ fraction. The column densities along several lines of sight are determined and discussd in the framework of chemical models.

A Model for Atomic and Molecular Interstellar Gas: The Meudon PDR Code [PDF]
Astrophysical Journal, Supplement Series, 2006 We present the revised ``Meudon'' model of Photon Dominated Region (PDR code), presently available on the web under the Gnu Public Licence at: http://aristote.obspm.fr/MIS. General organisation of the code is described down to a level that should allow most observers to use it as an interpretation tool with minimal help from our part.

DIFFUSE ATOMIC AND MOLECULAR GAS IN THE INTERSTELLAR MEDIUM OF M82 TOWARD SN 2014J [PDF]
Astrophysical Journal, 2015 We present a comprehensive analysis of interstellar absorption lines seen in moderately-high resolution, high signal-to-noise ratio optical spectra of SN 2014J in M82. Our observations were acquired over the course of six nights, covering the period from ~6 days before to ~30 days after the supernova reached its maximum B-band brightness.

Thermal Phases of the Neutral Atomic Interstellar Medium from Solar Metallicity to Primordial Gas [PDF]
Astrophysical Journal, 2019 Abstract We study the thermal structure of the neutral atomic (H i) interstellar medium across a wide range of metallicities, from supersolar down to vanishing metallicity, and for varying UV intensities and cosmic-ray (CR) ionization rates.

A DETAILED STUDY OF THE MOLECULAR AND ATOMIC GAS TOWARD THE γ-RAY SUPERNOVA REMNANT RX J1713.7−3946: SPATIAL TeV γ-RAY AND INTERSTELLAR MEDIUM GAS CORRESPONDENCE [PDF]
Astrophysical Journal, 2012 RX J1713.7-3946 is the most remarkable TeV {gamma}-ray supernova remnant (SNR) that emits {gamma}-rays in the highest energy range. We have made a new combined analysis of CO and H I in the SNR and derived the total protons in the interstellar medium (ISM).
