JWST/MIRI-MRS view of the metal-poor galaxy CGCG 007-025: the spatial location of PAHs and very highly ionized gas
Macarena G. del Valle-Espinosa, Matilde Mingozzi, Bethan James +16
Polycyclic Aromatic Hydrocarbons (PAHs) are key diagnostics of the physical conditions in the interstellar medium and are widely used to trace star formation in the mid-infrared (m…
Spatially Resolving the Fundamental Elements of Reionization in Galaxies
Xinfeng Xu, Stephan McCandliss, Allison Strom +10
Cosmic reionization marks a critical epoch when the first galaxies ionized the intergalactic medium through the escape of Lyman continuum (LyC) radiation. Young, massive star clust…
Exploring the mysterious high-ionization source powering [Ne V] in high-z analog SBS0335-052 E with JWST/MIRI
Matilde Mingozzi, Macarena Garcia Del Valle-Espinosa, Bethan L. James +19
Nearby blue compact dwarf galaxies (BCDs) share similar properties with objects from the Epoch of Reionization revealed by JWST, in terms of low stellar mass, low metallicity and h…
JWST/MIRI detection of [Ne V] and [Ne VI] in M83: Evidence for the long sought-after AGN?
Svea Hernandez, Linda J. Smith, Logan H. Jones +16
We report the first detections of [Ne V] 14.3 μm and [Ne VI] 7.7 μm at high confidence (S/N>=6) in the nuclear region of the nearby spiral galaxy M83. Emission line maps of these…
A JWST/MIRI View of the ISM in M83: I. Resolved Molecular Hydrogen Properties, Star Formation, and Feedback
Logan H. Jones, Svea Hernandez, Linda J. Smith +11
We present a spatially-resolved (~3 pc pix) analysis of the distribution, kinematics, and excitation of warm H2 gas in the nuclear starburst region of M83. Our JWST/MIRI IFU…
