Amplified capture rate of dark matter in compact binaries and constraints on bosonic dark matter from GW170817
János Takátsy, Lorenz Zwick, David O'Neill +1
The accretion of dark matter (DM) onto compact objects and the potential gravitational collapse of neutron stars due to this accretion has become a promising indirect probe of DM p…
Dissecting environmental effects with eccentric gravitational wave sources
Lorenz Zwick, Kai Hendriks, David O'Neill +6
We model the effect of resonances between time-varying perturbative forces and the epi-cyclical motion of eccentric binaries in the gravitational wave (GW) driven regime. These ind…
The construction and use of dephasing prescriptions for environmental effects in gravitational wave astronomy
János Takátsy, Lorenz Zwick, Kai Hendriks +3
In the first part of this work, we provide a curated overview of the theoretical framework necessary for incorporating dephasing due to environmental effects (EE) in gravitational…
Environmental effects in stellar mass gravitational wave sources I: Expected fraction of signals with significant dephasing in the dynamical and AGN channels
Lorenz Zwick, János Takátsy, Pankaj Saini +5
We present the first overview of the expected quantity of signals which will showcase significant gravitational wave phase shifts caused by astrophysical environments, considering…
Eccentricity distributions of eccentric binary black holes in galactic nuclei
János Takátsy, Bence Bécsy, Peter Raffai
Galactic nuclei are expected to be one of the main sites for formations of eccentric binary black holes (EBBHs), with an estimated detection rate of yr…
