A Hierarchical Shock Model of Ultra-High-Energy Cosmic Rays

Kavli Affiliate: Roger Blandford | Summary:We propose that a hierarchical shock model$unicodex2014$including supernova remnant shocks, galactic wind termination shocks, and accretion shocks around cosmic filaments and galaxy clusters$unicodex2014$can naturally explain the cosmic ray spectrum from ~1 GeV up to ~200 EeV. While this framework applies to the entire cosmic ray spectrum, in this work, we […]

Cosmic Reionization on Computers: Statistical Properties of the Distributions of Mean Opacities

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Ella Werre, David Robinson, Camille Avestruz, Nickolay Y. Gnedin, | Summary: Quasar absorption lines provide a unique window to the relationship between galaxies and the intergalactic medium during the Epoch of Reionization. In particular, high redshift quasars enable measurements of the neutral hydrogen content of the […]

Hybrid Agents for Image Restoration

Kavli Affiliate: Li Xin Li | First 5 Authors: Bingchen Li, Xin Li, , , | Summary: Existing Image Restoration (IR) studies typically focus on task-specific or universal modes individually, relying on the mode selection of users and lacking the cooperation between multiple task-specific/universal restoration modes. This leads to insufficient interaction for unprofessional users and […]

Why Prompt Design Matters and Works: A Complexity Analysis of Prompt Search Space in LLMs

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Juntai Cao, Jiaqi Wei, Chenyu You, Dujian Ding | Summary: Despite the remarkable successes of large language models (LLMs), the underlying Transformer architecture has inherent limitations in handling complex reasoning tasks. Chain-of-thought (CoT) prompting has emerged as a practical workaround, but most CoT-based methods rely […]
