Title: 大射电阵列中微子探测（GRAND）合作组——对第39届国际宇宙线会议（ICRC 2025）的贡献

Abstract: The Giant Radio Array for Neutrino Detection (GRAND) is an envisioned observatory of ultra-high-energy particles of cosmic origin, with energies in excess of 100 PeV. GRAND uses large surface arrays of antennas to look for the radio emission from extensive air showers that are triggered by the interaction of ultra-high-energy cosmic rays, gamma rays, and neutrinos in the atmosphere or underground. In particular, for ultra-high-energy neutrinos, the future final phase of GRAND aims to be sensitive enough to detect them in spite of their plausibly tiny flux. Three prototype GRAND radio arrays have been in operation since 2023: GRANDProto300, in China, GRAND@Auger, in Argentina, and GRAND@Nan\c{c}ay, in France. Their goals are to field-test the GRAND detection units, understand the radio background to which they are exposed, and develop tools for diagnostic, data gathering, and data analysis. This list of contributions to the 39th International Cosmic Ray Conference (ICRC 2025) presents an overview of GRAND, in its present and future incarnations, and a first look at data collected by GRANDProto300 and GRAND@Auger, including the first cosmic-ray candidates detected by them.

Abstract: 宇宙中高能粒子的巨型射电阵列（GRAND）是一个设想中的观测站，用于探测能量超过100 PeV的宇宙起源超高能粒子。 GRAND使用大型天线表面阵列来寻找由超高能宇宙射线、伽马射线和中微子在大气或地下相互作用引发的广延空气簇射的无线电辐射。 特别是对于超高能中微子，GRAND未来最终阶段的目标是具备足够的灵敏度，即使它们的通量可能非常小也能检测到它们。 自2023年以来，三个GRAND无线电阵列原型已经在运行：位于中国的GRANDProto300，位于阿根廷的GRAND@Auger，以及位于法国的GRAND@Nançay。 它们的目标是现场测试GRAND探测单元，了解它们所暴露的无线电背景，并开发用于诊断、数据收集和数据分析的工具。 这份提交给第三十九届国际宇宙射线会议（ICRC 2025）的贡献列表概述了GRAND目前和未来的形态，并首次展示了GRANDProto300和GRAND@Auger收集的数据，包括它们检测到的第一个宇宙射线候选者。
