## TL;DR

This paper investigates potential Lorentz violations in gravitational waves, exploring their signatures such as dispersion and birefringence, and deriving how these violations could affect signals detected from astrophysical sources.

## Contribution

The paper develops plane-wave solutions for Lorentz-violating linearized gravity and identifies observable signatures in gravitational wave signals.

## Key findings

- Lorentz violations cause dispersion and birefringence in gravitational waves
- Modifications to signals from coalescing binaries are derived
- Potential signatures in gravitational-wave detectors are identified

## Abstract

Lorentz violations in gravitational waves are investigated. Plane-wave solutions for arbitrary gauge-invariant violations in linearized gravity are constructed. Signatures of Lorentz violation include dispersion, birefringence, and anisotropies. Modifications to waves from coalescing compact binaries and to strain signals in gravitational-wave detectors are derived.
