Calculating the static gravitational two-body potential to fifth post-Newtonian order with Feynman diagrams
Stefano Foffa, Pierpaolo Mastrolia, Riccardo Sturani +2
We discuss the first-time calculation of the static gravitational two-body potential up to fifth post-Newtonian(PN) order. The results are achieved through a manifest factorization…
Logarithmic tail contributions to the energy function of circular compact binaries
Luc Blanchet, Stefano Foffa, François Larrouturou +1
We combine different techniques to extract information about the logarithmic contributions to the two-body conservative dynamics within the post-Newtonian (PN) approximation of Gen…
Science Case for the Einstein Telescope
Michele Maggiore, Chris van den Broeck, Nicola Bartolo +15
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,…
Gaussian processes reconstruction of modified gravitational wave propagation
Enis Belgacem, Stefano Foffa, Michele Maggiore +1
Recent work has shown that modified gravitational wave (GW) propagation can be a powerful probe of dark energy and modified gravity, specific to GW observations. We use the techniq…
Nonlocal gravity and gravitational-wave observations
Enis Belgacem, Yves Dirian, Andreas Finke +2
We discuss a modified gravity model which fits cosmological observations at a level statistically indistinguishable from CDM and at the same time predicts very large deviations…
Testing modified gravity at cosmological distances with LISA standard sirens
E. Belgacem, G. Calcagni, M. Crisostomi +18
Modifications of General Relativity leave their imprint both on the cosmic expansion history through a non-trivial dark energy equation of state, and on the evolution of cosmologic…
