Decomposition of Schwarzschild Green's Function
Junquan Su, Neev Khera, Marc Casals +3
We present a formulation of the spherically decomposed Green's function for a Schwarzschild black hole, based on a decomposition into two components, and , based on thei…
Gravitational memory meets astrophysical environments: exploring a new frontier through osculations
Rishabh Kumar Singh, Shailesh Kumar, Abhishek Chowdhuri +1
We study how dark matter environments influence nonlinear gravitational memory from intermediate-mass-ratio binaries. Incorporating environmental effects from the dark matter gravi…
Quasi-Keplerian parametrization for compact binaries on hyperbolic orbits in scalar-tensor theories at second post-Newtonian order
Davide Usseglio, David Trestini, Abhishek Chowdhuri
We obtain the generalized quasi-Keplerian parametrization for compact binaries on quasihyperbolic orbits at second post-Newtonian (2PN) order in a class of massless scalar-tensor t…
Exploring waveforms with non-GR deviations for extreme mass-ratio inspirals
Shailesh Kumar, Rishabh Kumar Singh, Abhishek Chowdhuri +1
The fundamental process of detecting and examining the polarization modes of gravitational waves plays a pivotal role in enhancing our grasp on the precise mechanisms behind their…
