题目:The Imaging X-ray Polarimetry Explorer (IXPE)
摘要:The next NASA Small Explorer (SMEX) mission, IXPE ( Imaging X-ray Polarimetry Explorer) , will be launched in 2021, with three identical X-ray mirror module assemblies and Gas Pixel Detectors (GPD). IXPE introduces the capability for X-ray polarimetric imaging, uniquely enabling the measurement of X-ray polarisation with scientifically meaningful spatial, spectral, and temporal resolution. During its baseline two-year operation, IXPE will have polarisation measurements on a few dozen sources, including various types of neutron stars, blackhole systems, active galactic nuclei, and supernova remnants, help to probe the origin and destiny of our universe. A series of simulation activities together with the calibration for flight units are in progress. The polarimeter design and expected performance will be discussed.
个人简历:2016年于中国科学院高能物理研究所获得博士学位,博士期间的课题是关于HXMT和SVOM的在轨工作性能和本底研究。之后两年在瑞典皇家理工学院从事博士后研究,主要参与的项目有由欧空局ESA主导的气体偏振探测器XIPE和瑞典空间局主导的伽马暴偏振探测器SPHiNX。目前工作于意大利国家天体物理研究所INAF,参与NASA即将于2021年发射的X射线偏振成像望远镜IXPE的研制,在合作组内负责标定数据分析和模拟以及本底研究。
