Cosmological and lunar laser ranging constraints on evolving dark energy in a nonminimally coupled curvature-matter gravity model
Riccardo March, Miguel Barroso Varela, Orfeu Bertolami +3
We analyze a cosmological solution to the field equations of a modified gravity model where curvature and matter are nonminimally coupled. The current Universe's accelerated expans…
Projective path to points at infinity in spherically symmetric spacetimes
Donato Bini, Giampiero Esposito
This paper proves that, in a four-dimensional spherically symmetric spacetime manifold, one can consider coordinate transformations expressed by fractional linear maps which give r…
Wedging spacetime principal null directions
D. Bini, A. Geralico, R. T. Jantzen
Taking wedge products of the distinct principal null directions associated with the eigen-bivectors of the Weyl tensor associated with the Petrov classification, when linearly…
Radiation-reaction and angular momentum loss at the second Post-Minkowskian order
Donato Bini, Thibault Damour
We compute the variation of the Fokker-Wheeler-Feynman total linear and angular momentum of a gravitationally interacting binary system under the second post-Minkowskian retarded d…
Radiated momentum and radiation-reaction in gravitational two-body scattering including time-asymmetric effects
Donato Bini, Thibault Damour, Andrea Geralico
We compute to high post-Newtonian accuracy the 4-momentum (linear momentum, and energy), radiated as gravitational waves in a two-body system undergoing gravitational scattering. W…
First Post-Minkowskian approach to turbulent gravity
Donato Bini, Stuart Kauffman, Sauro Succi +1
We compute the metric fluctuations induced by a turbulent energy-matter tensor within the first order Post-Minkowskian approximation. It is found that the turbulent energy cascade…
Predicting today's cosmological constant via the Zel'dovich-Holographic connection
Pablo G. Tello, Donato Bini, Stuart Kauffman +1
This Letter proposes a solution of the Vacuum Energy and the Cosmological Constant (CC) paradox based on the Zel'dovich's ansatz, which states that the observable contribution to t…
Multipolar invariants and the eccentricity enhancement function parametrization of gravitational radiation
Donato Bini, Andrea Geralico
Gravitational radiation can be decomposed as an infinite sum of radiative multipole moments, which parametrize the waveform at infinity. The multipolar-post-Minkowskian formalism p…
Momentum recoil in the relativistic two-body problem: higher-order tails
Donato Bini, Andrea Geralico
In the description of the relativistic two-body interaction, together with the effects of energy and angular momentum losses due to the emission of gravitational radiation, one has…
Static and Dynamic Melvin Universes
Donato Bini, Bahram Mashhoon
We briefly review the known properties of Melvin's magnetic universe and study the propagation of test charged matter waves in this static spacetime. Moreover, the possible corresp…
Gravitomagnetic Helicity
Donato Bini, Bahram Mashhoon, Yuri N. Obukhov
Mass currents in astrophysics generate gravitomagnetic fields of enormous complexity. Gravitomagnetic helicity, in direct analogy with magnetic helicity, is a measure of entwining…
Cassini and extra force constraints to nonminimally coupled gravity with screening mechanism
Riccardo March, Orfeu Bertolami, Marco Muccino +2
We consider a nonminimally coupled curvature-matter gravity theory at the Solar System scale. Both a fifth force of Yukawa type and a further non-Newtonian extra force that arises…
Petrov type I spacetime curvature: principal null vector spanning dimension
Donato Bini, Andrea Geralico, Robert T. Jantzen
The class of Petrov type I curvature tensors is further divided into those for which the span of the set of distinct principal null directions has dimension four (maximally spannin…
Frequency domain analysis of the gravitational wave energy loss in hyperbolic encounters
Donato Bini, Andrea Geralico
The energy radiated (without the 1.5PN tail contribution which requires a different treatment) by a binary system of compact objects moving in a hyperboliclike orbit is computed in…
Higher-order tail contributions to the energy and angular momentum fluxes in a two-body scattering process
Donato Bini, Andrea Geralico
The need for more and more accurate gravitational wave templates requires taking into account all possible contributions to the emission of gravitational radiation from a binary sy…

The linear-order effects of radiation-reaction on the classical scattering of two point masses, in General Relativity, are derived by a variation-of-constants method. Explicit expr…

A recently introduced approach to the classical gravitational dynamics of binary systems involves intricate integrals (linked to a combination of nonlocal-in-time interactions with…

Paolo Salucci, Giampiero Esposito, Gaetano Lambiase +38
In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of?, th…
