Fast radio bursts (FRBs) are the brightest millisecond-duration-astronomical transients in radio bands with yet unknown origin. I will briefly review the development process of the field of fast radio bursts and introduce how we use FAST to study fast radio bursts. We reveal systematic frequency evolution of repeating FRBs, namely depolarization toward lower frequencies, which can be well described by multi-path scatter, with only one single adjustable parameter σRM. Such a unified description of repeating FRBs indicates a complex environment near and/or around the bursting sources. Finally, I will introduce some polarization measurements of repeating FRBs.


I earned my bachelor's degree in physics from Tsinghua University in 2013, followed by a doctoral degree in astrophysics from the University of the Chinese Academy of Sciences in 2021. My research interests include: fast radio bursts, detecting gravitational waves using pulsar timing arrays, and computational astronomy. I have published more than 50 papers in top astronomy journals. I won the 2022’s Outstanding Science and Technology Achievement Prize of the Chinese Academy of Sciences, TR35, and First Prize of Beijing Natural Science Award.
