Reading Between the Dots: Decoding Hidden Computation across Filler Tokens
Kaley Brauer, Claudio Mayrink Verdun, Samuel Marks
Frontier LLMs can perform multi-step reasoning over content-free filler tokens like dots or counting sequences, producing correct answers with no visible chain-of-thought (CoT). Th…
Unraveling Chemical Enrichment in Extreme Emission-Line Galaxies: A Multi-Element Bayesian View of Bursty Star Formation and Galaxy Evolution in DESI
Razieh Emami, James A. A. Trussler, Tiger Yu-Yang Hsiao +11
Extreme emission-line galaxies (EELGs) probe chemical enrichment in low-mass, bursty systems where star formation, feedback, and gas accretion are poorly constrained. Using DESI DR…
The shape and spin state of (275677) 2000 RS11 from ground-based radar and optical observations
Richard E. Cannon, Agata Rożek, Kaley Brauer +12
Near-Earth asteroid (275677) 2000 RS11 was observed over 5 days in March 2014 with both the Arecibo (2380 MHz, 12.6 cm) and Goldstone (8560 MHz, 3.5 cm) planetary radar systems. Th…
From Simulations to Surveys: Domain Adaptation for Galaxy Observations
Kaley Brauer, Aditya Prasad Dash, Meet J. Vyas +2
Large photometric surveys will image billions of galaxies, but we currently lack quick, reliable automated ways to infer their physical properties like morphology, stellar mass, an…
Aeos: The Impact of Population III Initial Mass Function and Star-by-Star Models in Galaxy Simulations
Kaley Brauer, Jennifer Mead, John H. Wise +7
We explore the effect of variations in the Population III (Pop III) initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the Aeos sim…
EDGE-INFERNO: How chemical enrichment assumptions impact the individual stars of a simulated ultra-faint dwarf galaxy
Eric P. Andersson, Martin P. Rey, Robert M. Yates +6
The chemical abundances of stars in galaxies are a fossil record of the star formation and stellar evolution processes that regulate galaxy formation, including the stellar initial…
