H2 emission in the Orion Bar, NGC7023 and the Horsehead Nebula observed with the James Webb Space Telescope
M. Zannese, A. Sidhu, A. Guerras +25
Molecular hydrogen (H2), the most abundant molecule in the interstellar medium, is a handy tool to study Photodissociation Regions. The JWST, with its high spatial resolution, sens…
Mapping the Cosmic-Ray Ionization Rate in the Local Galaxy with H
Nick Indriolo, Alexei V. Ivlev, T. Pellegrin +6
Chemistry in diffuse molecular clouds relies primarily on rapid ion-molecule reactions. Formation of the initial ions, H and H, is dominated by cosmic-ray ionization of H…
The Resolved Structure of a Low Metallicity Photodissociation Region
Ilyse Y. Clark, Karin Sandstrom, Mark Wolfire +14
Photodissociation Regions (PDRs) are key to understanding the feedback processes that shape interstellar matter in galaxies. One important type of PDR is the interface between HII…
A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk
Olivier Berné, Emilie Habart, Els Peeters +143
Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
Identifying physical structures in our Galaxy with Gaussian Mixture Models: An unsupervised machine learning technique
M. Tiwari, R. Kievit, S. Kabanovic +14
We explore the potential of the Gaussian Mixture Model (GMM), an unsupervised machine learning method, to identify coherent physical structures in the ISM. The implementation we pr…
The chemistry of chlorine-bearing species in the diffuse interstellar medium, and new SOFIA/GREAT observations of HCl
David A. Neufeld, Helmut Wiesemeyer, Mark J. Wolfire +6
We have revisited the chemistry of chlorine-bearing species in the diffuse interstellar medium with new observations of the HCl molecular ion and new astrochemical models. Usin…
Thermal Pressure in the Cold Neutral Medium of Nearby Galaxies
R. Herrera-Camus, A. Bolatto, M. Wolfire +14
Dynamic and thermal processes regulate the structure of the multi-phase interstellar medium (ISM), and ultimately establish how galaxies evolve through star formation. Thus, to con…
Ubiquitous argonium (ArH) in the diffuse interstellar medium -- a molecular tracer of almost purely atomic gas
Peter Schilke, David A. Neufeld, Holger S. P. Müller +14
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…
