中科院高能物理研究所张双南教授来访并作学术报告
Prof. Shuangnan Zhang from IHEP visited SWIFAR
5月3日，应中国西南天文研究所邀请，慧眼卫星首席科学家张双南教授访问了中国西南天文研究所。
下午，张双南教授在研究所会议室作了题为“慧眼-硬X射线调制望远镜介绍：中国首个X射线天文卫星”的学术报告。他说，慧眼卫星是中国第一颗X射线天文卫星，于2017年6月15日成功发射。在其运行的不到一年时间里，它对银河系盘面多次扫描，发现和监测了多个高能天体，包括中子星，黑洞，伽玛射线暴等，并为2017年的双中子星引力波事件贡献了重要的数据。
晚上，张双南教授在信息学院报告厅作了题为“百年物理学、引力波和慧眼天文卫星”的专题讲座。张教授说，相对论和量子力学是现代物理学的两大基础。自1922年以来，研究相对论的物理学家仅有爱因斯坦获奖。2017年诺贝尔物理奖授予了对激光干涉引力波天文台和发现引力波作出了决定性贡献的三位物理学家：韦斯、索恩和巴里什。引力波成为了广义相对论中最后一个被证实的预言。2017年，天文学界还有一个重大发现，就是探测到了两个中子星相爱的雷鸣电闪。我国于2017年6月15号发射的慧眼天文卫星不仅为此次里程碑事件贡献了重要数据，更为将来引力波的探测打下了坚实的基础。全校200余名师生参加了报告会。张教授语言幽默诙谐，报告会现场气氛热烈。
张双南教授简介：
张双南教授，1989年在英国南安普敦大学获博士学位，1989年—1992年在美国宾西法尼亚大学做博士后。2002-2009年，清华大学特聘教授，2008年入选教育部长江学者特聘教授计划。现任中国科学院高能物理研究所研究员，博士生导师，中国科学院粒子天体物理重点实验室主任，科技部973项目“黑洞以及其它致密天体物理的研究”首席科学家。
Invited by SWIFAR, Prof. Shuangnan Zhang, the chief scientist of the Insight-HXMT, visited SWIFAR on May 3rd, 2018.
Prof. Shuangnan Zhang gave a colloquium on “Introduction to Insight-HXMT: Chinese first X-ray Astronomy Satellites” at SWIFAR in the afternoon. Being the first X-ray Astronomy Satellite, Insight-HXMT was successfully launched on June 15th, 2017. Within less than a year, it has scanned the Galactic disk for multiple times, and discovered and monitored many high-energy astrophysical objects, including Neutron Stars, Black Holes and Gamma-ray Bursts. Insight-HXMT has also contributed important data set for constraining the physical properties of GW170817, the famous gravitational wave event from a binary neutron-star merger.
In the evening, Prof. Shuangnan Zhang gave a public lecture in the auditorium of the Information Institute. The title is “Centennial physics, Gravitational Wave and Insight-HXMT”. In the lecture, he reviewed the history of the development of Relativity and Quantum Mechanics, the two foundations of modern physics. He discussed the recent breakthrough of the gravitational wave detections, which not only provides the last piece of puzzle to the theory of General Relativity, but also opens a new window for probing the nature of the cosmos. The detection of the electromagnetic counterpart of GW170817 marks the beginning of the multi-messenger era. Insight-HXMT has played an important role in this milestone event, demonstrating its powerfulness in future studies. More than 200 faculty members and students participated in this intriguing lecture.
Personal Information:
Shuangnan Zhang obtained his bachelor degree from Tsinghua University (Beijing, China) in 1984 and PhD degree from Southampton University in UK in 1989. He spent three years as a postdoc at University of Pennsylvania. He joined the BATSE/CGRO team in 1992. From 1998 to 2002, he was a faculty member of University of Alabama at Huntsville. In 2002 he moved back to China as a distinguished professor in Tsinghua University. Since 2009, he has become the director of the Division for and the Key Laboratory of Particle Astrophysics in IHEP, CAS. He is the PI of POLAR, Insight-HXMT and a few future large space missions (e.g. eXTP and HERD), and the Chinese Co-PI of SVOM.
