Dongzi Li (Caltech) "The mystery of fast radio burst, the potential and the limit"
Fast Radio Bursts (FRBs) are extremely energetic, millisecond-duration radio bursts coming outside our galaxy. The burst arrival time at different frequencies implies the number of electrons it has encountered in the foreground. Therefore, FRB is considered a promising new cosmological probe. The uncertainty of the circum-burst environment is one of the biggest concerns regarding its potential as a probe. In this talk, I will discuss the current understanding of the FRB progenitor and the recent study of the circum-burst environment. I will also briefly discuss its potential and limit as a probe to improve our understanding of the universe.
