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…
A Definitive Determination of the Interstellar Carbon Abundance toward rho Ophiuchi A and B
Adam M. Ritchey, S. R. Federman, Daniel E. Welty +1
We present the results of an effort to derive interstellar gas-phase C II abundances along the lines of sight toward rho Oph A and B. Our analysis is based on high-resolution NUV a…
JWST observations of photodissociation regions. IV. Carbonaceous emission band sub-components in NGC 7023 have distinct spatial distributions
D. Van De Putte, K. D. Gordon, K. Misselt +10
We analyze JWST spectroscopy of the northwest filament of NGC7023, where the relatively soft radiation field results in a photodissociation region with an extended atomic hydrogen…
JWST MIRI-MRS observations of the Red Rectangle: AIB class transformation in the outer nebula
A. Ebenbichler, P. Moraga Baez, A. Candian +8
Aims: We characterize the mid-infrared spectrum of the outer regions of the Red Rectangle nebula to probe the carbonaceous dust and molecular content beyond the circumbinary disk.…
JWST observations of photodissociation regions III. Dust modelling at the illuminated edge of the Horsehead PDR
M. Elyajouri, A. Abergel, N. Ysard +19
Carbonaceous nano-grains are a significant component of interstellar dust and dominate the mid-infrared emission of photodissociation regions (PDRs). We study the evolution of nano…
JWST observations of photodissociation regions: II. Warm molecular Hydrogen spectroscopy in the Horsehead nebula
M. Zannese, P. Guillard, A. Abergel +16
H2 is the most abundant molecule in the interstellar medium and is a useful tool to study photodissociation regions, where radiative feedback from massive stars on molecular clouds…
Resolving Emission from Small Dust Grains in the Blue Compact Dwarf II Zw 40 with JWST
Thomas S. -Y. Lai, Sara Duval, J. D. T. Smith +15
We present James Webb Space Telescope (JWST) Near Infrared Spectrograph (NIRSpec) and Mid-infrared Instrument (MIRI) integral-field spectroscopy of the nearby blue compact dwarf II…
JWST Observations of Photo-dissociation Regions. II. Aliphatic/Aromatic Carbonaceous Dust, Ices, and Gas Phase Spectral Line Inventory
K. Misselt, A. N. Witt, K. D. Gordon +10
This paper provides an overview of the spectroscopic data obtained by the JWST Guaranteed Time Observations (GTO) program 1192, "The Physics and Chemistry of PDR Fronts", including…
JWST observations of the Horsehead photon-dominated region I. First results from multi-band near- and mid-infrared imaging
A. Abergel, K. Misselt, K. D. Gordon +14
The JWST has captured the sharpest IR images ever taken of the Horsehead nebula, a prototypical moderately irradiated PDR that is fully representative of most of the UV-illuminated…
The 3D Geometry of Reflection Nebulae IC 59 and IC 63 with their illuminating Star Gamma Cas
Jacob M. Eiermann, Miranda Caputo, Thomas S. -Y. Lai +1
The early-type star Cas illuminates the reflection nebulae IC 59 and IC 63, creating two photo-dissociation regions (PDRs). Uncertainties about the distances to the nebulae and…
PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula
Emilie Habart, Els Peeters, Olivier Berné +139
The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypic…
