# VERITAS Observations of Fast Radio Bursts

## TL;DR

This paper discusses VERITAS observations of fast radio bursts, focusing on their properties, the challenges in observing them, and the results from targeted multiwavelength follow-up of known repeating FRBs.

## Contribution

It introduces the VERITAS FRB observing program and reports on the results of these targeted high-energy observations.

## Key findings

- No high-energy counterparts detected during observations.
- Constraints placed on high-energy emission models for FRBs.
- Enhanced understanding of FRB emission mechanisms.

## Abstract

Fast radio bursts (FRBs) are bright, unresolved, millisecond-duration flashes of radio emission originating from outside of the Milky Way. The source of these mysterious outbursts is unknown, but their high luminosity, high dispersion measure and short duration requires an extreme, high-energy, astrophysical process. The majority of FRBs have been discovered as single events which would require a chance coincidence for contemporaneous multiwavelength observations. However, two have been observed to repeat: FRB 121102 and the recently detected FRB 180814.J0422+73. These repeating FRBs have allowed for targeted observations by a number of different instruments, including VERITAS. We present the VERITAS FRB observing program and the results of these observations.
