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…
Deus Ex Statistica: A Statistical Solution to the binary-binary Outcome of the Chaotic, Non-Hierarchical Four-Body Problem
Yoav Zack, Hagai B. Perets, Yonadav Barry Ginat
We present an analytical, statistical solution to the binary-binary (2+2) outcome of the chaotic non-hierarchical four-body problem. The solution is based on the density-of-states…
Second-Generation Mass Peak in the Gravitational-Wave Population as a Probe of Globular Clusters
Yonadav Barry Ginat, Fabio Antonini, Elizabeth Flanagan +1
Gravitational-wave observations have revealed an excess of binary black hole mergers with primary masses near . We show that if this feature originates from dynam…
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…
Apparent Dark-Energy Evolution from Cosmic Inhomogeneities
Yonadav Barry Ginat, Pedro G. Ferreira
A mildly inhomogeneous universe with a cosmological constant may look like it contains evolving dark energy. We show that could be the case by modelling the inhomogeneities and the…
