Supernova Kinetic Yield oN galactic Emission Tracers (SKYNET) I. Contribution of radiative supernova remnants to Galactic N + emission
Guillaume Vigoureux, Benjamin Godard, Antoine Gusdorf +1
Context. The radiative stage of a supernova remnant (SNR) constitutes approximately 90% of its lifetime. Yet, only a few tens of radiative supernova remnants (r-SNRs) have been obs…
The Neutral Atomic Hydrogen in the solar neighborhood (NeAtHood) project I. Ghost in the shell: Neutral atomic hydrogen in the extended Orion nebula
J. D. Soler, H. Beuther, S. C. O. Glover +15
The Orion Nebula is the nearest site of ongoing and recent high-mass star formation. It is a unique laboratory for studying the mass, energy, and momentum input from high-mass star…
Multiphase turbulence as the origin of OH+, H2O+ and H3+ column density scatter in the local ISM
Uri Malamud, Shmuel Bialy, Benjamin Godard +2
Observations of the reactive ions OH+, H2O+ and H3+ in the Galactic interstellar medium reveal large sight-line-to-sight-line scatter in their column densities, commonly interprete…
The Multi-phase HI of the Milky Way and Nearby Galaxies
Marc-Antoine Miville-Deschênes, J. R. Dawson, Narendra Nath Patra +30
Atomic hydrogen (HI) is the dominant baryonic component of the interstellar medium (ISM) in Milky Way-like galaxies and the reservoir from which molecular clouds and stars ultimate…
Velocity-resolved [O I] 63,145 um, [C II] 158 um, and OH mapping along the Orion BN/KL explosive outflow and irradiated shocks
J. R. Goicoechea, R. Güsten, B. Godard +6
Stellar mergers produce explosive outflows that serve as transient sources of IR line luminosity and inject mechanical energy early into the natal molecular cloud. We present the f…
Turning JWST/MIRI backgrounds into a survey of diffuse molecular hydrogen
E. Nigou, B. Godard, P. Guillard +3
Context. A statistically significant sampling of H2 rotational excitation in the diffuse interstellar medium (ISM) is essential to identifying its excitation mechanisms and assessi…
JWST observations of cosmic-ray-excited H in Barnard 68: spatial variations and constraints on cosmic-ray attenuation
David A. Neufeld, Kedron Silsbee, Alexei V. Ivlev +9
We present James Webb Space Telescope (JWST) NIRSpec observations of the starless dark cloud Barnard 68 that reveal the spatially-resolved signature of cosmic-ray excited molecular…
The first detection of cosmic-ray excited H in interstellar space
Shmuel Bialy, Amit Chemke, David A. Neufeld +12
Stars and planets form within cold, dark molecular clouds. In these dense regions, where starlight cannot penetrate, cosmic rays (CRs) are the dominant source of ionization -- driv…
Supernova Shocks in Molecular Clouds: Shocks Driven into Dense Cores in IC 443 and 3C 391
William T. Reach, Ngoc Le Tram, Curtis DeWitt +3
Supernova shocks into dense molecular cores in IC 443 (clumps B, C, and G) and 3C 391 were observed using the Stratospheric Observatory for Infrared Astronomy and complemented by a…
Physical conditions in Centaurus A's northern filaments II: Does the HCO emission highlight the presence of shocks?
Quentin Salomé, Philippe Salomé, Benjamin Godard +2
Abridged: We present the first observation of the HCO+(1-0) and HCN(1-0) emission in the northern filaments of Centaurus A with ALMA. HCO+(1-0) is detected in 9 clumps of the Horse…
The Molecular Cloud Lifecycle I: Constraining H2 formation and dissociation rates with observations
Shmuel Bialy, Blakesley Burkhart, Daniel Seifried +9
Molecular clouds (MCs) are the birthplaces of new stars in galaxies. A key component of MCs are photodissociation regions (PDRs), where far-ultraviolet radiation plays a crucial ro…
Shocks in the warm neutral medium II -- Origin of neutral carbon at high pressure
Benjamin Godard, Guillaume Pineau Des Forêts, Jeremy La Porte +1
Aims: Ultraviolet (UV) lines of neutral carbon observed in absorption in the local diffuse interstellar medium (ISM) have long revealed that a substantial fraction of the mass of t…
Radiative and mechanical energies in galaxies I. Contributions of molecular shocks and PDRs in 3C 326 N
J. A. Villa-Vélez, B. Godard, P. Guillard +1
Context: Atomic and molecular lines in galaxies offer insights into energy budgets and feedback mechanisms. Aims: This study establishes a new framework for interpreting these line…
Shocks in the warm neutral medium I -- Theoretical model
Benjamin Godard, Guillaume Pineau Des Forêts, Shmuel Bialy
Context. Atomic and molecular line emissions from shocks may provide valuable information on the injection of mechanical energy in the interstellar medium (ISM), the generation of…
