Fast Radio Bursts (FRBs) are bright (≳1Jy), ubiquitous, radio flashes with millisecond duration from cosmological origin. About seven hundred FRBs have been published since the first discovery in 2007, of which fifty sources have been observed with complex repetitions. About twenty FRBs have been localized to their host galaxies by interferometries, and only four of them have been pinpointed by the VLBI to local environments, including globular clusters and persistent radio sources. Hence, the nature of FRBs is still puzzling.
FRBs show very diverse properties in observations. To understand their local environment and cosmological distribution, using VLBI outrigger stations to localize non-repeating FRBs with a milli-arcsecond resolution has been proposed. In addition, the Bustling Universe Radio Survey Telescope in Taiwan (BURSTT), a next-generation telescope with new beamforming techniques, could monitor FRBs with an all-sky field-of-view that the survey area is at least 100 times more than any of the current FRB surveys. Upcoming BURSTT phase 1 is expected to detect ~100 bright and nearby FRBs per year, with major upgrades planned. Combining the all-sky FRBs survey with VLBI outriggers, BURSTT’s large sample with milli-arcsecond localizations will answer several open questions about FRBs. In this talk, I will review the progress of the FRB field in the past decade, discuss a few highlighted repeaters, and outline the future of the upcoming FRB era.
