Particle Cosmology Group

Introduction

Anhui Provincial Astronomical Society will organize an annual conference on the Jan 23-26, 2026 in Qianshan, Anqing city. The conference is to summarize what particle cosmology field has achieved in the past whole year and to provide an excellent opportunity for the researchers to present their works in the way of oral talks. Any researchers, graduate and undergraduate students in the field of particle cosmology are most welcome to join us.

安徽省天文学会拟于2026年1月23日至26日在安徽省潜山市举办2026年度安徽省天文学会粒子宇宙学学术研讨会暨小规模射电阵列天文台址勘测会议。本次会议旨在讨论近年来国内外粒子宇宙学领域的研究进展成果，促进学术交流与合作，推动学科发展。会议将结合学术报告和研讨交流为主要形式，欢迎相关领域的专家、学者及研究生踊跃参加。
