CAS: A Causal Attribution Score for Local and Global Explainable Artificial Intelligence
Michael Georgiades, Charalambia Varnava
Predictive explanation methods attribute a model output; they do not, by themselves, attribute an intervention effect on the real-world outcome. We introduce the Causal Attribution…
GLOW II: A Census of Oxygen in Low-Mass Galaxies
Kristen B. W. McQuinn, O. Grace Telford, Andrey V. Kravtsov +12
Oxygen is forged by stars and redistributed through galaxies by feedback-driven outflows, leaving a record of star formation and the baryon cycle imprinted on its present-day abund…
Scylla: Observational Evidence for an Order of Magnitude in Dust Mass Opacity Evolution with ISM Density in the Large Magellanic Cloud
Christina W. Lindberg, Christopher J. R. Clark, Claire E. Murray +11
The emissivity of dust is known to vary greatly with radiative environment, density, grain chemistry, and geometry. Discrepancies between dust mass surface densities derived from f…
COS2035: Extending COS/FUV Operations Through the 2030s
Marc Rafelski, David Sahnow, Christian I. Johnson +29
The paper outlines the COS2035 plan to keep the Cosmic Origins Spectrograph far‑ultraviolet detector functional into the 2030s by introducing new calibration methods, a flexible li…
Dust in the very metal-poor galaxy Sextans A with JWST. I: Characterizing the evolved stellar population of Sextans A based on JWST observations and stellar evolution models
C. Gavetti, F. Dell'Agli, E. Tarantino +22
The nearby star-forming dwarf galaxy Sextans A offers a unique window into galaxy evolution in the early Universe, owing to its extremely low metallicity (about 1-7% Zsun). Recent…
The Panchromatic Hubble Andromeda Southern Treasury (PHAST). II. The Spatially Resolved Recent Star Formation History in M31
Tobin M. Wainer, Benjamin F. Williams, Zhuo Chen +19
We use Hubble Space Telescope optical imaging from the Panchromatic Hubble Andromeda Southern Treasury (PHAST) to measure the spatially resolved recent star formation history (SFH)…
