FRB Searches with the Irish LOFAR Station

TL;DR

This paper reports a search for low-frequency radio emissions from known fast radio burst sources using the Irish LOFAR station, resulting in null detections after extensive observations.

Contribution

It presents the first extensive low-frequency search for FRB emissions with the Irish LOFAR station, covering over 200 hours of data from 2020 to 2022.

Findings

No radio emission was detected from the six FRB sources.

The observations set upper limits on low-frequency FRB emissions.

The study demonstrates the capabilities of the Irish LOFAR station for FRB searches.

Abstract

Here we report null results in the search for radio emission below $200$~MHz from six known fast radio burst sources. The observations reported here were taken using the Irish LOFAR station's high-band antennas over the course of 2020, 2021 and 2022; the cumulative observing time was $218$~h.
