How general relativity stacks up: Testing gravity by coherently combining gravitational-wave observations
Lachlan Passenger, Nir Guttman, Paul D. Lasky +1
A core mission of gravitational-wave astronomy is to test general relativity (GR) in the high-curvature, high-velocity regime. The field has already seen significant progress in th…
The Sun's chemical peculiarity: disentangling Galactic chemical evolution and planetary engulfment in solar twins
Mia Babatsikos, Fan Liu, Amanda Karakas +5
Recent observational studies have suggested that the Sun may be chemically peculiar relative to the majority of solar twins. Here, we re-analyse high-resolution, high signal-to-noi…
Is GW231123 a hierarchical merger?
Lachlan Passenger, Sharan Banagiri, Eric Thrane +4
The binary black hole merger GW231123 is both the most massive gravitational-wave event observed and has the highest component spins measured to date. The dimensionless spins of th…
A search for extra polarisations using a Gaussian process in Gravitational-Wave Transient Catalogue 3
Shun Yin Cheung, Lachlan Passenger, Paul D. Lasky +1
General relativity predicts that gravitational waves are described by two polarisation states: the plus state and cross state. However, alternate theories of gravity a…
A Gaussian process framework for testing general relativity with gravitational waves
Lachlan Passenger, Shun Yin Cheung, Nir Guttman +3
Gravitational-wave astronomy provides a promising avenue for the discovery of new physics beyond general relativity as it probes extreme curvature and ultra-relativistic dynamics.…
Are all models wrong? Falsifying binary formation models in gravitational-wave astronomy
Lachlan Passenger, Eric Thrane, Paul D. Lasky +3
As the catalogue of gravitational-wave transients grows, several entries appear "exceptional" within the population. Tipping the scales with a total mass of ,…
Possible Causes of False General Relativity Violations in Gravitational Wave Observations
Anuradha Gupta, K. G. Arun, Enrico Barausse +40
General relativity (GR) has proven to be a highly successful theory of gravity since its inception. The theory has thrivingly passed numerous experimental tests, predominantly in w…
