成像X射线偏振探测器（IXPE）通过同时将偏振测量添加到当前测量的源属性（能量，时间和位置）阵列来扩展观测空间。因此，IXPE将为理解天体如何产生X射线发射开辟新的维度，特别是在极端物理条件下的系统，如中子星和黑洞。极化奇异探测物理各向异性有序磁场，非球面物质分布，或广义相对论耦合到黑洞自旋，否则无法测量。因此，IXPE补充了高能天体物理学的所有其他研究，为研究宇宙X射线源和过程以及将极端天体物理环境用作基础物理实验室的参数空间增加了重要和相对未探索的信息。
The Imaging X-ray Polarimetry Explorer (IXPE) expands observation space by simultaneously adding polarization measurements to the array of source properties currently measured (energy, time, and location). IXPE will thus open new dimensions for understanding how X-ray emission is produced in astrophysical objects, especially systems under extreme physical conditions—such as neutron stars and black holes. Polarization singularly probes physical anisotropies—ordered magnetic fields, aspheric matter distributions, or general relativistic coupling to black-hole spin—that are not otherwise measurable. Hence, IXPE complements all other investigations in high-energy astrophysics by adding important and relatively unexplored information to the parameter space for studying cosmic X-ray sources and processes, as well as for using extreme astrophysical environments as laboratories for fundamental physics.
