Black Hole Dynamics at Fifth Post-Newtonian Order
Rafael A. Porto, Massimiliano M. Riva
Using the worldline action in [2409.05860], we derive the total even-in-velocity (relative) impulse, scattering angle, and time delay at fifth post-Newtonian (5PN) order, including…
Nonlinear Relativistic Tidal Response of Neutron Stars
Paolo Pani, Massimiliano Maria Riva, Luca Santoni +2
We investigate the nonlinear tidal response of relativistic neutron stars by computing the fully relativistic, static, quadratic Love numbers. Using both the worldline effective fi…
Vanishing of Quadratic Love Numbers of Schwarzschild Black Holes
Simon Iteanu, Massimiliano Maria Riva, Luca Santoni +2
The induced conservative tidal response of self-gravitating objects in general relativity is parametrized in terms of a set of coefficients, which are commonly referred to as Love…
Nonlinear Gravitational Radiation Reaction: Failed Tail, Memories & Squares
Rafael A. Porto, Massimiliano M. Riva, Zixin Yang
Using the Schwinger-Keldysh "in-in" effective field theory (EFT) framework, we complete the knowledge of nonlinear gravitational radiation-reaction effects in the (relative) dynami…
Vanishing of Nonlinear Tidal Love Numbers of Schwarzschild Black Holes
Massimiliano Maria Riva, Luca Santoni, Nikola Savić +1
It is well known that asymptotically flat Schwarzschild black holes in general relativity in four spacetime dimensions have vanishing induced linear tidal response. We extend this…
Angular momentum balance in gravitational two-body scattering: Flux, memory, and supertranslation invariance
Massimiliano Maria Riva, Filippo Vernizzi, Leong Khim Wong
Two puzzles continue to plague our understanding of angular momentum balance in the context of gravitational two-body scattering. First, because the standard definition of the Bond…
Classical vs Quantum Eikonal Scattering and its Causal Structure
Brando Bellazzini, Giulia Isabella, Massimiliano Maria Riva
We study the eikonal scattering of two gravitationally interacting bodies, in the regime of large angular momentum and large center of mass energy. We show that eikonal exponentiat…
Gravitational bremsstrahlung from spinning binaries in the post-Minkowskian expansion
Massimiliano Maria Riva, Filippo Vernizzi, Leong Khim Wong
We present a novel calculation of the four-momentum that is radiated into gravitational waves during the scattering of two arbitrarily spinning bodies. Our result, which is accurat…
Gravitational Bremsstrahlung with tidal effects in the post-Minkowskian expansion
Stavros Mougiakakos, Massimiliano Maria Riva, Filippo Vernizzi
We compute the mass and current quadrupole tidal corrections to the four-momentum and energy flux radiated during the scattering of two spinless bodies, at leading order in and…
Effective Field Theory for Gravitational Radiation in General Relativity and beyond
Massimiliano Maria Riva
The topic of this thesis is the so-called Non-Relativistic General Relativity, an effective field theory approach proposed by Goldberger and Rothstein to study the conservative and…
Radiated momentum in the Post-Minkowskian worldline approach via reverse unitarity
Massimiliano Maria Riva, Filippo Vernizzi
We compute the four-momentum radiated during the scattering of two spinless bodies, at leading order in the Newton's contant and at all orders in the velocities, using the Effe…
Gravitational Bremsstrahlung in the Post-Minkowskian Effective Field Theory
Stavros Mougiakakos, Massimiliano Maria Riva, Filippo Vernizzi
We study the gravitational radiation emitted during the scattering of two spinless bodies in the post-Minkowskian Effective Field Theory approach. We derive the conserved stress-en…
