The Irreversible Depletion of Dark Matter Spikes by Extreme-Mass-Ratio Inspirals
Charlie Sharpe, Yonadav Barry Ginat, Thomas F. M. Spieksma +2
Dense dark matter spikes around massive black holes (MBHs) have been widely predicted to produce gravitational-wave dephasing in extreme-mass-ratio inspirals (EMRIs) that are poten…
The Depletion of Collisionless Dark Matter Spikes
Charlie Sharpe, Yonadav Barry Ginat, Thomas F. M. Spieksma +2
Dense concentrations of dark matter surrounding black holes provide a compelling opportunity to probe the nature of dark matter. In the classic Gondolo--Silk model, the adiabatic g…
Resonant Locking Between Binary Systems Induced by Gravitational Waves
Charlie Sharpe, Yonadav Barry Ginat, Zeyuan Xuan +1
The interaction of gravitational waves (GWs) with matter is thought to be typically negligible in the Universe. We identify an exception in the case of resonant interactions, where…
The Equivalence Principle and The Cosmological Constant Problem
Yonadav Barry Ginat
In this essay I point out that, in the context of semi-classical gravity, the equivalence principle can mitigate the cosmological constant problem. On a Minkowski space-time backgr…
Multiple-Scales Approach to The Averaging Problem in Cosmology
Yonadav Barry Ginat
The Universe is homogeneous and isotropic on large scales, so on those scales it is usually modelled as a Friedmann-Lemaître-Robertson-Walker (FLRW) space-time. The non-linearity o…
Axion oscillations in binary systems: angle-action surgery
Vincent Desjacques, Evgeni Grishin, Yonadav Barry Ginat
Scalar, tensor waves induce oscillatory perturbations in Keplerian systems that can be probed with measurements of pulsar timing residuals. In this paper, we consider the imprint o…
