The FAST Galactic Plane Pulsar Snapshot Survey: II. Discovery of 76 Galactic rotating radio transients and their enigma

Understand

We are carrying out the GPPS survey by using the FAST, the most sensitive systematic pulsar survey in the Galactic plane.

• In addition to about 500 pulsars already discovered through normal periodical search, we report here the discovery of 76 new transient radio sources with sporadic strong pulses, detected by using the newly developed module for a sensitive single pulse search.
• Their small DM values suggest that they all are the Galactic RRATs.
• More radio pulses have been detected from 26 transient radio sources but no periods can be found due to a limited small number of pulses from all FAST observations.
