TL;DR

This paper explores using intermediate-mass black hole binary inspirals to perform a robust Ryan test of general relativity early in the inspiral phase, demonstrating feasibility and identifying optimal system parameters.

Contribution

It introduces a method to perform a theoretically robust Ryan test with intermediate-mass black holes using early inspiral data, which was previously unexplored.

Findings

Feasibility of performing the Ryan test with IMBH binaries.

Identification of the most favorable system parameters.

Potential for early detection and testing of general relativity.

Abstract

We investigate the possibility of using binary IMBH inspirals to perform the Ryan test of general relativity in a theoretically robust manner using data from early in the detectable part of the inspiral. We find this to be feasible and compute the masses of the most favourable systems.
