Follow-up of the First Fast Radio Burst Discovered with Arecibo

Fast radio bursts (FRBs) are a new class of short-duration radio bursts discovered in archival data from pulsar surveys. FRBs may represent a new class of astrophysical sources at extragalactic distances ­ inferred from their large dispersion measures. Seven FRBs are now in the published literature with the first six discovered by the Parkes Radio Telescope in Australia. Recently, Arecibo became the first independent telescope to confirm the existence of FRBs when a burst was discovered by the Pulsar ALFA survey. No repeat events have been seen from any FRB sky position, although most follow-up has been fairly limited. We propose to follow-up the Arecibo FRB with a larger field-of-view, more time, and greater range of observing frequencies than has been done for any other FRB. As repeatability (or lack thereof ) is crucial to understanding the nature of these sources, systematic and thorough follow-up is essential. Outreach Abstract: Seven years ago a new astrophysical phenomena was discovered by radio telescopes. They are brief flashes of radio waves that last for only one-thousandth of a second and were dubbed fast radio bursts. Radio astronomers currently believe that these bursts originate in far away galaxies. What kind of astrophysical ob ject causes these flashes is still a big mystery, but candidates include exploding neutron stars or flares from highly-magnetic pulsars. Arecibo recently discovered its first fast radio burst, and because there is so little known about what these are, it is important to look at the same position to see if we see any further bursts. This proposal requests to conduct further observations in the direction of the Arecibo burst.

Remote Observing Request

Observer will travel to AO X Remote Observing In Absentia (instructions to operator)

Section I I - Time Request
The following times are in LST. For these observations night-time is not needed.

Begin ­ End Interval ­ Interval 04:34:51­06:31:24 ­ ­ ­

Days Needed at This Interval 5

Time Constraints (Must Be Justified in the Prop osal Text) The observations should be logarithmically spaced; the interval between observations should increase by, say, factors of two: 1 day, 2 days, 4 days, etc.

Section I I I - Instruments Needed
327 ALFA

Atmospheric Observation Instruments: 2


Sp ecial Equipment or setup: Both ALFA and the 327 MHz receivers are needed for each session.

Section IV - RFI Considerations Frequency Ranges Planned
302 - 352 1214 - 1536 This proposal requires coordination with Punta Salinas radar within the band 1222-1381 MHz.. This proposal requires coordination with GPS L3 at 1381 MHz.
