Abstract: 

Fast radio bursts (FRBs) are bright milliseconds radio transients with large dispersion measures (DMs), and can be used as cosmological tools. Many models for FRB progenitors have been proposed. However, none of them can explain all the observational properties, meaning that FRBs remain one of the most intriguing mysteries in astronomy. The statistical properties of radio bursts can unveil the underlying physics. In this talk, I will present some progress on FRBs, including physical models, statistical properties and cosmological applications. Besides, some models predict that high-energy explosions (such as gamma-ray bursts and supernovae) are associated with FRBs. Exploring such ancient explosions by radiocarbon in tree ring is also discussed.
