Curtin, , , | Summary: The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) project has discovered the most repeating fast radio burst (FRB) sources of any telescope. However, most of the physical conclusions derived from this sample are based […]
Kavli Affiliate: Joseph Falson | Summary:High temperatures promote kinetic processes which can drive crystal synthesis towards ideal thermodynamic conditions, thereby realizing samples of superior quality. While accessing very high temperatures in thin-film epitaxy is becoming increasingly accessible through laser-based heating methods, demonstrations of such utility are still emerging. Here we realize a novel self-regulated growth […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zijian Zhang, Linhua Jiang, Weiyang Liu, Luis C. Ho, | Summary: James Webb Space Telescope (JWST) has revealed a population of red and compact sources at $z gtrsim 5$ known as “Little Red Dots” (LRDs) that are likely active galactic nuclei (AGNs). Here we present a […]
Kavli Affiliate: Linhua Jiang | Summary:James Webb Space Telescope (JWST) has revealed a population of red and compact sources at $z gtrsim 5$ known as “Little Red Dots” (LRDs) that are likely active galactic nuclei (AGNs). Here we present a comprehensive study of the variability of 314 LRDs with multi-epoch JWST observations in five deep […]
Kavli Affiliate: Anthony Lasenby | Summary:Spherically symmetric Einstein-æther (EÆ) theory with a Maxwell-like kinetic term is revisited. We consider a general choice of the metric and the æther field, finding that:~(i) there is a gauge freedom allowing one always to use a diagonal metric; and~(ii) the nature of the Maxwell equation forces the æther field […]
Kavli Affiliate: Wei Gao| Summary:In the past year, video-based large language models (Video LLMs) have achieved impressive progress, particularly in their ability to process long videos through extremely extended context lengths. However, this comes at the cost of significantly increased computational overhead due to the massive number of visual tokens, making efficiency a major bottleneck. […]
Kavli Affiliate: Norbert Schulz | Summary:Cosmic dust plays a crucial role in the evolution of galaxies, significantly influencing star formation and the interstellar medium. However, in active galactic nuclei (AGN), the role and origin of dust remain poorly understood. High-resolution X-ray spectroscopy is a powerful tool for probing the properties of dust in AGN. NGC […]
Kavli Affiliate: Ran Wang | First 5 Authors: Fuxiang Xu, Ran Wang, Jianan Li, Roberto Neri, Antonio Pensabene | Summary: We present NOrthern Extended Millimeter Array observations of CO(8-7), (9-8), and (10-9) lines, as well as the underlying continuum for two far-infrared luminous quasars: SDSS J2054-0005 at $rm z=6.0389$ and SDSS J0129-0035 at $rm z=5.7788$.

Kavli Affiliate: Jing Wang | First 5 Authors: Peng Tang, Jiacheng Liu, Xiaofeng Hou, Yifei Pu, Jing Wang | Summary: The Mixture-of-Experts (MoE) architecture has demonstrated significant advantages in the era of Large Language Models (LLMs), offering enhanced capabilities with reduced inference costs. However, deploying MoE-based LLMs on memoryconstrained edge devices remains challenging due to […]
