The Eccentric Behavior of Inspiraling Compact Binaries
Nicholas Loutrel, Samuel Liebersbach, Nicolas Yunes +1
Eccentricity of binary systems is not a gauge invariant quantity, but has an important impact on the observed gravitational wave signal of such systems, generating power in all pos…
Gravitational Waveforms for Precessing, Quasicircular Compact Binaries with Multiple Scale Analysis: Small Spin Expansion
Katerina Chatziioannou, Antoine Klein, Nicolas Yunes +1
We obtain analytical gravitational waveforms in the frequency-domain for precessing, quasi-circular compact binaries with small spins, applicable, for example, to binary neutron st…
The NANOGrav 15-year Data Set: Bayesian Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +96
Evidence for a low-frequency stochastic gravitational wave background has recently been reported based on analyses of pulsar timing array data. The most likely source of such a bac…
Chaos in Quantum Cosmology
Neil Cornish, Paul Shellard
Much of the foundational work on quantum cosmology employs a simple minisuperspace model describing a Friedmann-Robertson-Walker universe containing a massive scalar field. We show…
A Rosetta Stone for Parameterized Tests of Gravity
Laura Sampson, Nicolas Yunes, Neil Cornish
Several model-independent parameterizations of deviations from General Relativity have been developed to test Einstein's theory. Although these different parameterizations were dev…
The Princess and the Pea
Neil Cornish, Norm Frankel
Like a fairy-tale princess, trajectories around black holes can be sensitive to small disturbances. We describe how a small disturbance can lead to erratic orbits and an increased…
