Multi-Agent System for Cosmological Parameter Analysis

Kavli Affiliate: Blake Sherwin | First 5 Authors: Andrew Laverick, Kristen Surrao, Inigo Zubeldia, Boris Bolliet, Miles Cranmer | Summary: Multi-agent systems (MAS) utilizing multiple Large Language Model agents with Retrieval Augmented Generation and that can execute code locally may become beneficial in cosmological data analysis. Here, we illustrate a first small step towards AI-assisted […]

A gravitational wave detectable candidate Type Ia supernova progenitor

Kavli Affiliate: Erin Kara | First 5 Authors: Emma T. Chickles, Kevin B. Burdge, Joheen Chakraborty, Vik S. Dhillon, Paul Draghis | Summary: Type Ia supernovae, critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evidence supports the “double-degenerate” scenario, where two white dwarfs […]

Interacting Dark Sector (ETHOS $n=0$): Cosmological Constraints from SPT Cluster Abundance with DES and HST Weak Lensing Data

Kavli Affiliate: Lindsey Bleem | First 5 Authors: Asmaa Mazoun, Sebastian Bocquet, Joseph J. Mohr, Mathias Garny, Henrique Rubira | Summary: We use galaxy cluster abundance measurements from the South Pole Telescope (SPT) enhanced by Multi-Component Matched Filter (MCMF) confirmation and complemented with mass information obtained using weak-lensing data from Dark Energy Survey Year~3 (DES […]

Signatures of black hole seeding in the local Universe: Predictions from the BRAHMA cosmological simulations

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K Bhowmick, Laura Blecha, Paul Torrey, Rachel S Somerville, Luke Zoltan Kelley | Summary: The first "seeds" of supermassive black holes (BHs) continue to be an outstanding puzzle, and it is currently unclear whether the imprints of early seed formation survive today. Here we examine the […]
