PDRs4All XIII. Empirical prescriptions for the interpretation of JWST imaging observations of star-forming regions
Ryan Chown, Yoko Okada, Els Peeters +17
(Abridged) JWST continues to deliver incredibly detailed infrared (IR) images of star forming regions in the Milky Way and beyond. IR emission from star-forming regions is very spe…
The Resolved Behavior of Dust Mass, Polycyclic Aromatic Hydrocarbon Fraction, and Radiation Field in ~ 800 Nearby Galaxies
Jérémy Chastenet, Karin M. Sandstrom, Adam K. Leroy +8
We present resolved m dust spectral energy distribution (SED) fitting for nearby galaxies. We measure the distribution of radiation field intensities heating…
A First-look at Spatially-resolved Infrared Supernova Remnants in M33 with JWST
Sumit K. Sarbadhicary, Erik Rosolowsky, Adam K. Leroy +12
We present the first spatially-resolved infrared images of supernova remnants (SNRs) in M33 with the unprecedented sensitivity and resolution of JWST. We analyze 40 SNRs in four JW…
Polycyclic Aromatic Hydrocarbon and CO(2-1) Emission at 50-150 pc Scales in 70 Nearby Galaxies
Ryan Chown, Adam K. Leroy, Karin Sandstrom +44
Combining Atacama Large Millimeter/sub-millimeter Array CO(2-1) mapping and JWST near- and mid-infrared imaging, we characterize the relationship between CO(2-1) and polycyclic aro…
PDRs4All. X. ALMA and JWST detection of neutral carbon in the externally irradiated disk d203-506: Undepleted gas-phase carbon
Javier R. Goicoechea, J. Le Bourlot, J. H. Black +26
The gas-phase abundance of carbon, x_C = C/H, and its depletion factors are essential parameters for understanding the gas and solid compositions that are ultimately incorporated i…
The Local Group L-Band Survey: The First Measurements of Localized Cold Neutral Medium Properties in the Low-Metallicity Dwarf Galaxy NGC 6822
Nickolas M. Pingel, Hongxing Chen, Snežana Stanimirović +15
Measuring the properties of the cold neutral medium (CNM) in low-metallicity galaxies provides insight into heating and cooling mechanisms in early Universe-like environments. We r…
The Fraction of Dust Mass in the Form of PAHs on 10-50 pc Scales in Nearby Galaxies
Jessica Sutter, Karin Sandstrom, Jérémy Chastenet +21
Polycyclic aromatic hydrocarbons (PAHs) are a ubiquitous component of the interstellar medium (ISM) in z~0 massive, star-forming galaxies and play key roles in ISM energy balance,…
H-alpha emission and HII regions at the locations of recent supernovae in nearby galaxies
Ness Mayker Chen, Adam K. Leroy, Sumit K. Sarbadhicary +22
We present a statistical analysis of the local, approximately 50-100 pc scale, H-alpha emission at the locations of recent (less than 125 years) supernovae (SNe) in nearby star-for…
PDRs4All VIII: Mid-IR emission line inventory of the Orion Bar
Dries Van De Putte, Raphael Meshaka, Boris Trahin +135
Mid-infrared emission features probe the properties of ionized gas, and hot or warm molecular gas. The Orion Bar is a frequently studied photodissociation region (PDR) containing l…
PDRs4All IX. Sulfur elemental abundance in the Orion Bar
Asunción Fuente, Evelyne Roueff, Franck Le Petit +31
One of the main problems in astrochemistry is determining the amount of sulfur in volatiles and refractories in the interstellar medium. The detection of the main sulfur reservoirs…
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…
PDRs4All VII. The 3.3 m aromatic infrared band as a tracer of physical properties of the ISM in galaxies
Ilane Schroetter, Olivier Berné, Christine Joblin +9
Aromatic infrared bands (AIBs) are a set of broad emission bands at 3.3, 6.2, 7.7, 8.6, 11.2, and 12.7 m, seen in the infrared spectra of most galaxies. With JWST, the 3.3 m…
Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk
Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53
Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…
PDRs4All. V. Modelling the dust evolution across the illuminated edge of the Orion Bar
M. Elyajouri, N. Ysard, A. Abergel +31
We study the emission of dust grains within the Orion Bar - a well-known, highly far-UV (FUV)-irradiated PDR. The Orion Bar because of its edge-on geometry provides an exceptional…
PHANGS-JWST: Data Processing Pipeline and First Full Public Data Release
Thomas G. Williams, Janice C. Lee, Kirsten L. Larson +55
The exquisite angular resolution and sensitivity of JWST is opening a new window for our understanding of the Universe. In nearby galaxies, JWST observations are revolutionizing ou…
