Description

An annual survey of the astro-ph.CO arXiv category, covering research published from September 2025 – August 2026. Built on a close-reading set of 108 papers and organised into 40 chapters, it maps the year by the field's research sub-directions.

Book framework (share of the year's output):

Large-Scale Structure and Dark Matter Probes (35.3%) — 利用巡天、透镜和模拟研究宇宙大尺度结构形成、暗物质晕性质及非高斯统计。
Inflation and Early Universe Dynamics (19.2%) — 探索暴胀模型、标量场动力学及早期宇宙的引力波和原初扰动起源。
Dark Energy and Hubble Tension Constraints (18.0%) — 结合DESI、CMB等数据约束暗能量模型和哈勃常数张力。
Gravitational Waves and Primordial Black Holes (15.0%) — 研究引力波背景、脉冲星计时阵列信号及原初黑洞的形成与演化。
Cosmic Microwave Background and Reionization (8.2%) — 利用CMB功率谱、21厘米线和运动学SZ效应约束再电离历史和宇宙学参数。
Theoretical Cosmology and Quantum Effects (2.1%) — 研究微扰理论、量子涨落、轴子及对称性破缺等理论问题。
Machine Learning and Inference Methods (1.1%) — 开发深度学习、仿真器和统计推断工具以提升宇宙学分析精度。
Neutrino Physics and Nonlinear Dynamics (0.9%) — 研究中微子质量、衰变及非线性演化对宇宙学观测的影响。
Multi-Probe Synergy and Cosmological Origins (0.3%) — 整合多波段探针（引力波、21厘米、强透镜）以理解宇宙起源和基本物理。

Each sub-direction is covered across three chapters — how it framed its questions, the strength of its key findings, and its open debates and frontiers — so the reader gets a traceable picture of what this part of the field actually produced over the year.
