Title
Mysteries of fast radio bursts
Reporter

Description
In 2007, a mysterious millisecond-duration burst was found around the cellphone band. This kind of signal is now known as fast radio burst (FRB), energetic bursts visible at a cosmological distance. Hundreds of more FRBs have been detected in the past 5 years with dedicated radio surveys. And FAST has become a major player in the FRB follow-ups due to its unprecedented sensitivity. In this talk, I will review the current understanding of the origin of FRBs, as well as the many remaining mysteries, including the location of the FRBs, the magneto-environment and the long-term periodicity. I will also introduce current and upcoming instruments which will detect more FRBs with orders of magnitude better spatial resolution. The result will be an explosion of opportunity for understanding burst origin and probing cosmic matter distribution at various spatial scales.
