# Constraints on Lorentz Invariance Violations from Gravitational Wave Observations

## TL;DR

This paper uses gravitational wave data from LIGO and Virgo to set constraints on Lorentz invariance violations and the graviton mass by analyzing binary black hole signals.

## Contribution

It presents a method to derive bounds on Lorentz invariance violations and graviton mass from gravitational wave observations, based on deformed dispersion relations.

## Key findings

- Constraints on Lorentz invariance violations established
- Upper bounds on graviton mass derived
- Method applied to 10 binary black hole detections

## Abstract

Using a deformed dispersion relation for gravitational waves, Advanced LIGO and Advanced Virgo have been able to place constraints on violations of local Lorentz invariance as well as the mass of the graviton. We summarise the method to obtain the current bounds from the 10 significant binary black hole detections made during the first and second observing runs of the above detectors.
