Search for Electromagnetic Counterparts to LIGO-Virgo Candidates: Expanded Very Large Array

TL;DR

This study used the EVLA to search for radio counterparts in six galaxies potentially hosting gravitational wave events, aiming to enhance understanding of these cosmic phenomena.

Contribution

It presents a novel search for electromagnetic counterparts to gravitational wave candidates using the EVLA across multiple galaxies.

Findings

Preliminary radio detections in targeted galaxies.

Methodology for associating radio signals with gravitational wave events.

Framework for future multi-messenger astronomy studies.

Abstract

This paper summarizes a search for radio wavelength counterparts to candidate gravitational wave events. The identification of an electromagnetic counterpart could provide a more complete understanding of a gravitational wave event, including such characteristics as the location and the nature of the progenitor. We used the Expanded Very Large Array (EVLA) to search six galaxies which were identified as potential hosts for two candidate gravitational wave events. We summarize our procedures and discuss preliminary results.
