Science Case for the Einstein Telescope

- M. Maggiore, C. V. D. Broeck, +15 authors M. Sakellariadou
- Physics
- 5 December 2019

The Einstein Telescope (ET), a proposed European ground-based gravitational-wave detector of third-generation, is an evolution of second-generation detectors such as Advanced LIGO, Advanced Virgo,… Expand

Nonlocal gravity. Conceptual aspects and cosmological predictions

- E. Belgacem, Y. Dirian, S. Foffa, M. Maggiore
- Physics
- 19 December 2017

Even if the fundamental action of gravity is local, the corresponding quantum effective action, that includes the effect of quantum fluctuations, is a nonlocal object. These nonlocalities are well… Expand

Effective field theory calculation of conservative binary dynamics at third post-Newtonian order

- S. Foffa, R. Sturani
- Physics
- 6 April 2011

We reproduce the two-body gravitational conservative dynamics at third post-Newtonian order for spinless sources by using the effective field theory methods for the gravitationally bound two-body… Expand

Effective field theory approach to the gravitational two-body dynamics at fourth post-Newtonian order and quintic in the Newton constant

- S. Foffa, P. Mastrolia, R. Sturani, C. Sturm
- Physics
- 1 December 2016

Working within the post-Newtonian (PN) approximation to general relativity, we use the effective field theory (EFT) framework to study the conservative dynamics of the two-body motion at fourth PN… Expand

Non-local gravity and comparison with observational datasets. II. Updated results and Bayesian model comparison with ΛCDM

- Y. Dirian, S. Foffa, M. Kunz, M. Maggiore, V. Pettorino
- Physics
- 10 February 2016

We present a comprehensive and updated comparison with cosmological observations of two non-local modifications of gravity previously introduced by our group, the so called RR and RT models. We… Expand

Dynamics of the gravitational two-body problem at fourth post-Newtonian order and at quadratic order in the Newton constant

- S. Foffa, R. Sturani
- Physics
- 29 June 2012

We derive the conservative part of the Lagrangian and the energy of a gravitationally bound two-body system at fourth post-Newtonian order, up to terms quadratic in the Newton constant. We also show… Expand

Tail terms in gravitational radiation reaction via effective field theory

- S. Foffa, R. Sturani
- Physics
- 23 November 2011

Gravitational radiation reaction affects the dynamics of gravitationally bound binary systems. Here we focus on the leading "tail" term which modifies binary dynamics at fourth post-Newtonian order,… Expand

Nonlocal gravity with a Weyl-square term

- G. Cusin, S. Foffa, M. Maggiore, Michele Mancarella
- Physics
- 20 December 2015

Recent work has shown that modifications of General Relativity based on the addition to the action of a non-local term $R\,\Box^{-2}R$, or on the addition to the equations of motion of a term… Expand

Cosmological perturbations and structure formation in nonlocal infrared modifications of general relativity

- Y. Dirian, S. Foffa, N. Khosravi, M. Kunz, M. Maggiore
- Physics
- 24 March 2014

We study the cosmological consequences of a recently proposed nonlocal modification of general relativity, obtained by adding a term $m^2R\,\Box^{-2}R$ to the Einstein-Hilbert action. The model has… Expand
