Fast Radio Bursts (FRBs) are mysterious, millisecond flashes of radio light of unknown origin from far outside the Milky Way. The nature of FRBs, including their emission mechanism and environment, is one of the most perplexing enigmas in astrophysics and a major front for research. To deepen the mystery, a subset of FRB sources emits multiple bursts, the so-called “repeaters,” while for most FRBs only one burst is observed. Their all-sky rate of ~1,000 per day suggests the phenomenon is ubiquitous.
There is no consensus about the FRB origin despite a large number of recent detections. Understanding these enigmatic new objects remains one of the most important missions of astronomy. Diverse progenitors have been proposed as the origin of FRBs, including white dwarfs, old neutron stars, old black holes, magnetars, young pulsars, supernovae remnants, and active supermassive black holes.
Previous observatories have been hampered by the following four problems
Lack of localization capability
Poor field of view
Missing FRBs due to narrow time windows
Mismatch with multi-messengers
BURSTT overcomes the four challenges with the following advantages
Accurate localization
Extremely wide field of view
Complete census of nearby FRBs with a long time window
Synergy with multi-messengers
Once the origin of FRBs is understood, FRBs can be employed as cosmic probes to address key science challenges
