A fast radio burst with a low dispersion measure

Understand

Fast radio bursts (FRBs) are millisecond pulses of radio emission of seemingly extragalactic origin.

• More than 50 FRBs have now been detected, with only one seen to repeat.
• Here we present a new FRB discovery, FRB 110214, which was detected in the high latitude portion of the High Time Resolution Universe South survey at the Parkes telescope.
• FRB 110214 has one of the lowest dispersion measures of any known FRB (DM = 168.9$\pm$0.5 pc cm$^{-3}$), and was detected in two beams of the Parkes multi-beam receiver.
