标题： Detection of extended TeV emission around the Geminga pulsar with H.E.S.S

摘要： 在Geminga脉冲星周围发现了高度扩展的伽马射线辐射，这一发现由Milagro证实，并由HAWC验证。尽管使用成像大气契伦科夫望远镜（IACTs）进行了许多观测，但检测超出IACT视场角度尺度的伽马射线辐射已被证明具有挑战性。分析技术的最新进展使得在H.E.S.S.的存档数据中检测到Geminga周围的显著辐射成为可能。2019年，通过采用调整后的观测策略，获得了Geminga区域的进一步数据。在宣布在存档数据中检测到Geminga周围显著的TeV辐射后，本文我们将展示在独立数据集中的检测结果。将介绍新的分析结果，并重点强调使用IACTs观测高度扩展的伽马射线辐射所涉及的技术挑战。 显示英文摘要

摘要： Highly extended gamma-ray emission around the Geminga pulsar was discovered by Milagro and verified by HAWC. Despite many observations with Imaging Atmospheric Cherenkov Telescopes (IACTs), detection of gamma-ray emission on angular scales exceeding the IACT field-of-view has proven challenging. Recent developments in analysis techniques have enabled the detection of significant emission around Geminga in archival data with H.E.S.S.. In 2019, further data on the Geminga region were obtained with an adapted observation strategy. Following the announcement of the detection of significant TeV emission around Geminga in archival data, in this contribution we present the detection in an independent dataset. New analysis results will be presented, and emphasis given to the technical challenges involved in observations of highly extended gamma-ray emission with IACTs.
