A Multi-telescope Campaign on FRB 121102: Implications for the FRB Population

Understand

We present results of the coordinated observing campaign that made the first subarcsecond localization of a Fast Radio Burst, FRB 121102.

• During this campaign, we made the first simultaneous detection of an FRB burst by multiple telescopes: the VLA at 3 GHz and the Arecibo Observatory at 1.4 GHz.
• Of the nine bursts detected by the Very Large Array at 3 GHz, four had simultaneous observing coverage at other observatories.
• We use multi-observatory constraints and modeling of bursts seen only at 3 GHz to confirm earlier results showing that burst spectra are not well modeled by a power law.
