Fast Radio Bursts (FRBs)

A short duration (~milliseconds), very energetic flash of radio emission. These were originally detected in pulsar surveys and were found to be of extragalactic origin. Since then we have found some which have repeated and one which has been localized to a dwarf galaxy (FRB 121102). While official NANOGrav activities does not specifically support FRB research, because of the long connection with pulsar timing personnel, many members of NANOGrav also work on FRBs. They may be useful analogues to understanding the pulsar emission mechanism and their propagation through the intergalactic medium parallels the processes of propagation through the interstellar medium.
