Chemical diversity of dense cores in Orion B: The role of the environment

Helena J. Mazurek, Maryvonne Gerin, Pierre Gratier +26

Prestellar cores are the sites of the earliest stages of star formation. Dust continuum observations are often used to identify and characterize their properties yet only a small f…

Spatial distribution of organics in the Horsehead nebula: Signposts of chemistry driven by atomic carbon

Claudio Hernández-Vera, Viviana V. Guzmán, Jérôme Pety +10

(Abridged) Complex organic molecules (COMs) are considered essential precursors to prebiotic species. While COMs were once expected to be efficiently destroyed under UV-irradiated…

PDRs4All XVII: Formation and excitation of HD in photodissociation regions. Application to the Orion Bar

Marion Zannese, Jacques Le Bourlot, Evelyne Roueff +12

The James Webb Space Telescope enabled the first detection of several rovibrational emission lines of HD in the Orion Bar, a prototypical photodissociation region. This provides an…

Spectral survey of the diffuse gas toward BL Lac in the Q band

Maryvonne Gerin, Harvey Liszt, Belen Tercero +1

The chemical composition of diffuse interstellar clouds is not fully established. They host an active chemistry despite their relatively low density and the ubiquitous presence of…

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…

Observations of Carbon Radio Recombination Lines with the NenuFAR telescope. I. Cassiopeia A and Cygnus A

Lucie Cros, Antoine Gusdorf, Philippe Salomé +26

Carbon Radio Recombination Lines (CRRLs) at decametre wavelengths trace the diffuse phase of the interstellar medium (ISM) of the Galaxy. Their observation allows to measure physic…
