Unveiling Metal Mixing in a Grand-Design Spiral: A UV-optical multiphase spatially resolved study of M83
Adarsh Ranjan, Bethan L. James, Svea Hernandez +4
We present a spatially resolved, multiphase study of chemical enrichment around young star clusters (YSCs) in the nearby grand-design spiral M83 by combining far-ultraviolet(UV) ab…
Exploring the synergies of with MUSE spectroscopy in PHANGS H II regions
Eric Habjan, Kathryn Kreckel, Christopher Faesi +16
Spatially resolved maps of gas-phase metallicity provide key constraints on the chemical enrichment and mixing processes that drive galaxy evolution, but measurements based only on…
Toward Unbiased Abundance Measurements in Inhomogeneous Regions
Eric Habjan, Christopher Faesi, Kathryn Kreckel +10
Probing the chemical content of the interstellar medium (ISM) in nearby galaxies provides key insight into their chemical evolution and informs our interpretation of galaxies at hi…
The First Empirical Calibration of the MIR Abundance Diagnostic Ne with JWST
Noah S. J. Rogers, Evan D. Skillman, Danielle A. Berg +10
Large surveys of galaxies in the local and high-redshift Universe have, traditionally, relied on the intensity of rest-optical emission lines from metal ions in the Interstellar Me…
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…
The Interstellar Medium in I Zw 18 seen with JWST/MIRI: II. Warm Molecular Hydrogen and Warm Dust
L. K. Hunt, B. T. Draine, M. G. Navarro +16
We present JWST/MIRI spectra from the Medium-Resolution Spectrometer of IZw18, a nearby dwarf galaxy with a metallicity of % Solar. Here, we investigate warm molecular hydr…
