JWST imaging of the Pleiades: anisotropy of turbulence in the cold neutral medium

G. Vigoureux, N. Flagey, F. Boulanger +14

Interstellar medium studies rely on magnetohydrodynamic (MHD) turbulence as a framework for interpretation. In this context, the statistical characterization of interstellar observ…

Shock excitation of H in the James Webb Space Telescope era

L. E. Kristensen, B. Godard, P. Guillard +2

(Abridged) H2 is the most abundant molecule in the Universe. Thanks to its widely spaced energy levels, it predominantly lights up in warm gas, T > 100 K, such as shocked regions,…

HyGAL: Characterizing the Galactic ISM with observations of hydrides and other small molecules II. The absorption line survey with the IRAM 30 m telescope

W. -J. Kim, P. Schilke, D. A. Neufeld +11

As a complement to the HyGAL Stratospheric Observatory for Infrared Astronomy Legacy Program, we report the results of a ground-based absorption line survey of simple molecules in…

3D chemical structure of the diffuse turbulent ISM II -- Origin of CH, new solution to an 80 years mystery

Benjamin Godard, Guillaume Pineau Des Forêts, Patrick Hennebelle +2

Aims: The large abundances of CH in the diffuse interstellar medium (ISM) are a long standing issue of our understanding of the thermodynamical and chemical states of the gas.…

HyGAL: Characterizing the Galactic ISM with observations of hydrides and other small molecules -- I. Survey description and a first look toward W3(OH), W3 IRS5 and NGC 7538 IRS1

A. M. Jacob, D. A. Neufeld, P. Schilke +22

The HyGAL SOFIA legacy program surveys six hydride molecules -- ArH+, OH+, H2O+, SH, OH, and CH -- and two atomic constituents -- C+ and O -- within the diffuse interstellar medium…
