Black hole spectroscopy: from theory to experiment
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Emanuele Berti, Vitor Cardoso, Gregorio Carullo, Jahed Abedi, Niayesh Afshordi | Summary: The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes and comparing them with gravitational-wave data from compact binary mergers […]

FSL-SAGE: Accelerating Federated Split Learning via Smashed Activation Gradient Estimation
Kavli Affiliate: Jia Liu | First 5 Authors: Srijith Nair, Michael Lin, Peizhong Ju, Amirreza Talebi, Elizabeth Serena Bentley | Summary: Collaborative training methods like Federated Learning (FL) and Split Learning (SL) enable distributed machine learning without sharing raw data. However, FL assumes clients can train entire models, which is infeasible for large-scale models. In […]

Basic Elements of Strong Gravitational Lensing
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Jeremy D. Schnittman, , , | Summary: Even when used to describe the same phenomenon, equations, graphics and words each give different perspectives and lead to complementary insights. The basic elements of strong gravitational lensing are introduced here favoring words and graphics over […]

Dust Budget Crisis in Little Red Dots
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kejian Chen, Zhengrong Li, Kohei Inayoshi, Luis C. Ho, | Summary: Little red dots (LRDs), a population of active galactic nuclei (AGNs) recently identified by JWST, are characterized by their compact morphology and red optical continuum emission, which is often interpreted as evidence for significant dust extinction […]

A black hole in a near-pristine galaxy 700 million years after the Big Bang
Kavli Affiliate: Debora Sijacki | First 5 Authors: Roberto Maiolino, Hannah Uebler, Francesco D’Eugenio, Jan Scholtz, Ignas Juodzbalis | Summary: The recent discovery of a large number of massive black holes within the first two billion years after the Big Bang, as well as their peculiar properties, have been largely unexpected based on the extrapolation […]

Soliton resolution for the coupled complex short pulse equation
Kavli Affiliate: Ran Wang | First 5 Authors: Nan Liu, Ran Wang, , , | Summary: We address the long-time asymptotics of the solution to the Cauchy problem of ccSP (coupled complex short pulse) equation on the line for decaying initial data that can support solitons. The ccSP system describes ultra-short pulse propagation in optical […]
