The HII Regions' Molecular Law of Star Formation

Daniela Calzetti, Drew Lapeer, Robert C. Kennicutt +28

We combine imaging data from the HST, JWST, and ground-based millimeter facilities to investigate the correlation between star formation rate (SFR) and molecular gas at the ~100 pc…

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…

FEAST: a NIRSpec/MOS survey of emerging young star clusters in NGC 628

Helena Faustino Vieira, Angela Adamo, Neville Shane +18

JWST can pierce through dusty molecular clouds to study the early stages of star formation, where young star clusters are actively driving stellar feedback and still emerging from…

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…

Quantification of The Age Dependence of Mid-Infrared Star Formation Rate Indicators

Daniela Calzetti, Robert C. Kennicutt, Angela Adamo +33

We combine James Webb Space Telescope images of the nearby galaxy NGC 5194 in the hydrogen recombination line Pa-alpha (lambda=1.8756 micron) from the Cycle 1 program JWST-FEAST wi…
