Fast radio burst science

Fast radio burst (FRB) is a hot topic at present. More than 100 FRBs have been reported, but their origins remain mysterious. Among all the bursts, some are found to repeat. The first repeater FRB 121102 was localized in a host galaxy with a redshift z = 0.19273(8), confirming the cosmological origin of FRBs. In this talk, I will first introduce the background of FRB, including the main discoveries and projects. Then, I will present our FRB searching projects cooperated with XAO and YNAO, the searching techniques and our results. We detected some strange perytons at Nanshan, which are a kind of RFI smilar with the real celestial radio signal. Recently,  we identified a new repeating FRB  and detected more than 100 burst from FRB 121102 in one hour using the FAST telescope.
