Tracers of the ionization fraction in dense and translucent molecular gas: II. Using mm observations to constrain ionization fraction across Orion B
Ivana Bešlić, Maryvonne Gerin, Viviana V. Guzmán +28
The ionization fraction () is a crucial parameter of interstellar gas, yet estimating it requires deep knowledge of molecular gas chemistry…
Rotational equilibrium of C in diffuse interstellar clouds
J. Le Bourlot, E. Roueff, S. R. Federman +2
Context. Recent spectroscopic measurements have revealed absorption from higher rotational levels in C than previous observations. These improvements are accompanied by the ava…
Beetroots: spatially-regularized Bayesian inference of physical parameter maps -- Application to Orion
Pierre Palud, Emeric Bron, Pierre Chainais +28
The current generation of millimeter receivers is able to produce cubes of 800 000 pixels by 200 000 frequency channels to cover several square degrees over the 3 mm atmospheric wi…
Inelastic H + H Collision rates and their impact in the determination of the excitation temperature of H
Daniel Felix-Gonzalez, Pablo del Mazo-Sevillano, Alfredo Aguado +5
Context. In dffuse interstellar clouds the excitation temperature derived from the lowest levels of H is systematically lower than that derived from H2. The differences may b…
A highly efficient Voigt program for line profile computation
Mofreh R. Zaghloul, Jacques Le Bourlot
Evaluation of the Voigt function, a convolution of a Lorentzian and a Gaussian profile, is essential in various fields such as spectroscopy, atmospheric science, and astrophysics.…
Toward a robust physical and chemical characterization of heterogeneous lines of sight: The case of the Horsehead nebula
Léontine Ségal, Antoine Roueff, Jérôme Pety +28
Dense cold molecular cores/filaments are surrounded by an envelope of translucent gas. Some of the low-J emission lines of CO and HCO isotopologues are more sensitive to the co…
