Abstract: 

Supernova remnants play an important role in galactic ecosystems by depositing substantial mechanical energy and driving chemical enrichment. These objects efficiently accelerate particles to high energies while modifying surrounding magnetic fields. This talk will cover a few topics of SNR research enabled by X-ray observations: Recent X-ray studies of SNRs reveal new insights into supernova progenitor systems and explosion mechanisms, helping us understand stellar death diversity. The IXPE mission's imaging X-ray polarimetric observations yield essential constraints on magnetic field structures and particle acceleration processes. In the next decade, new X-ray missions such as eXTP and HUBS are expected to greatly advance our knowledge in this field.

Ping Zhou is an associate professor at Nanjing University. She obtained her PhD at Nanjing University in 2014 and worked as a postdoc at the Anton Pannekoek Institute at the University of Amsterdam from 2016 to 2020. After that, she joined the faculty at the School of Astronomy and Space Science at Nanjing University. Her research focuses on supernova remnants, the interstellar medium, and isolated neutron stars. She has participated in the IXPE supernova remnant topical working group and joined the science groups of LHAASO (the Large High Altitude Air Shower Observatory, X-ray coordinator),  EP (Einstein Probe), and future X-ray missions eXTP (the enhanced X-ray Timing and Polarimetry) and HUBS (the Hot Universe Baryon Surveyor, co-chair of the Galactic Science working group).
