Using GALEX UV Excess to Search for Metal-poor Halo Stars
Chase L. Smith, Maxwell Moe, Megan Frank +10
Metal-poor solar-type stars display a significant reduction in metal-line blanketing at short wavelengths, leading to an excess of near-ultraviolet (NUV) flux compared to their met…
Survival of very small carbonaceous dust grains in the inner-CGM of NGC 891 from JWST/MIRI MRS
Jérémy Chastenet, Ilse De Looze, Karl D. Gordon +26
We present new spectroscopic observations of the inner circumgalactic medium (CGM) of NGC 891 taken with the Mid-Infrared Imager/Medium Resolution Spectroscopy instrument onboard J…
JWST Observations of Starbursts: Molecular Hydrogen Excitation and Disequilibrium in M82
Sara E. Duval, J. D. T. Smith, Alberto D. Bolatto +24
Emission from the pure rotational transitions of H traces warm molecular gas, providing insight into its temperature distribution and local heating conditions. We have extended…
Determining star formation histories and age-metallicity relations with convolutional neural networks
Enrique Galceran, Patricia Sánchez-Blázquez, Artemi Camps-Fariña +8
We aim to develop a state-of-the-art tool to infer detailed star formation histories (SFHs) and age-metallicity relations from realistic observational data, while mitigating classi…
JWST Observations of Starbursts: Dust Processing in the M82 Superwind
Serena A. Cronin, Alberto D. Bolatto, Helena M. Richie +39
We present JWST MIRI and NIRCam imaging of the inner ~5 kpc of the M82 superwind at 0.05-0.375'' (~0.9-6.5 pc) resolution. Targeted filters probe emission from polycyclic aromatic…
Nowhere Left to Hide: Uncovering All of the Massive Young Embedded Star Clusters in the Antennae with JWST
Rupali Chandar, Miranda Caputo, Paul Goudfrooij +15
The Antennae galaxies merger produces the brightest infrared emission of any galaxy within ~20 Mpc, mostly from intense star formation taking place in supergiant molecular cloud co…
