報告摘要:
Pulsar wind nebulae (PWNe) are powerful sources of non-thermal X-ray radiation, which is intrinsically polarized due to synchrotron emission. The magnetic field strength and structure in these sources play a crucial role in shaping their dynamics, energetics and evolution, as well as in accelerating particles to very high energies. X-ray polarimetry can provide unique insights into understanding the local orientation and degree of order of the magnetic field, as well as the distribution and spectrum of the emitting particles. In this talk, I will review the current status and future prospects of X-ray polarimetry applied to extended source PWN, with a focus on the Imaging X-ray Polarimetry Explorer (IXPE) mission, which is a NASA/ASI explorer launched in December 2021.
