Pulsar wind nebulae (PWN) and supernova remnants (SNR) 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. The Imaging X-ray Polarimetry Explorer (IXPE) is the first observatory fully dedicated to study the polarization of X-ray sources, with capabilities of spatially resolved X-ray polarimetry in 2-8 keV energy band. In this talk I will present the polarization results of IXPE observations of PWN and SNR.

Prof. Fei Xie obtained her Bachelor in Physics in 2011, PhD degree in Astrophysics in 2016 at University of Chinese Academic of Sciences. She was a postdoc at the KTH Royal Institute of Technology in Sweden and INAF/IAPS (Istituto di Astrofisica e Planetologia Spaziali) in Italy. In 2021, she joined Guangxi University and is now a professor at School of Physical Science and Technology. She works mainly on X-ray polarization detection technology and high energy astrophysics like pulsar wind nebula.
