ContraVis: Evidence-Grounded Visual Analytics for Contradiction Review in Legal Contracts

Luis Sante, Paula Lima, Mariana Rocha +1

Legal contracts are structurally complex documents in which contradictions may emerge across distant and interconnected provisions. Although large language models (LLMs) improve le…

Phase-Spirals Across Galactic Disks II: Using large-scale "macro-spirals" in phase-spiral amplitude to derive perturbation times

Kiyan Tavangar, Kathryn V. Johnston, Jason A. S. Hunt +3

Phase-space spirals in the Milky Way disk are a key observable remnant of recent perturbations to the Galaxy. They provide insight into the disk's potential, dynamical evolution, p…

A Broken Clock Is Right Twice a Day: [Ce/Mg] Is Not a Universal Chemical Clock

Liam O. Dubay, Jennifer A. Johnson, James W. Johnson +14

The ratio of -process to -element enrichment () has been proposed as a ``chemical clock,'' or a means to estimate stellar ages. However, the age-- relation vari…

The Milky Way's circular velocity curve measured using element abundance gradients

Danny Horta, Adrian M. Price-Whelan, Sergey E. Koposov +4

Spectroscopic surveys now supply precise stellar label measurements such as element abundances for large samples of stars throughout the Milky Way. These element abundances are kno…
