Formation Rate of Quasiperiodic Eruptions in Galactic Nuclei Containing Single and Dual Supermassive Black Holes

Kavli Affiliate: Xian Chen | First 5 Authors: Chunyang Cao, F. K. Liu, Xian Chen, Shuo Li, | Summary: Quasiperiodic eruptions (QPEs) are a novel class of transients recently discovered in a few extragalactic nuclei. It has been suggested that a QPE can be produced by a main-sequence star undergoing repeated partial disruptions by the […]

Neutrino Diffusion within Dark Matter Spikes

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Motoko Fujiwara, Gonzalo Herrera, Shunsaku Horiuchi, , | Summary: Multi-messenger observations of astrophysical transients provide powerful probes of the underlying physics of the source as well as beyond the Standard Model effects. We explore transients that can occur in the vicinity of supermassive black holes at the […]

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 […]
