A Bright Millisecond Radio Burst of Extragalactic Origin
@article{Lorimer2007ABM, title={A Bright Millisecond Radio Burst of Extragalactic Origin}, author={Duncan R. Lorimer and Matthew Bailes and Maura Mclaughlin and D J Narkevic and Fronefield Crawford}, journal={Science}, year={2007}, volume={318}, pages={777 - 780} }
Pulsar surveys offer a rare opportunity to monitor the radio sky for impulsive burst-like events with millisecond durations. We analyzed archival survey data and found a 30-jansky dispersed burst, less than 5 milliseconds in duration, located 3° from the Small Magellanic Cloud. The burst properties argue against a physical association with our Galaxy or the Small Magellanic Cloud. Current models for the free electron content in the universe imply that the burst is less than 1 gigaparsec distant…

A fast radio burst localized to a massive galaxy
- PhysicsNature
- 2019
Use of a specially built radio interferometer shows that a non-repeating fast radio burst is localized to a few-arcsecond region containing a single massive galaxy, and is perhaps derived from an old stellar population.
