Gravity in the infrared and effective nonlocal models
Enis Belgacem, Yves Dirian, Andreas Finke +2
We provide a systematic and updated discussion of a research line carried out by our group over the last few years, in which gravity is modified at cosmological distances by the in…
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…
Cosmology and dark energy from joint gravitational wave-GRB observations
Enis Belgacem, Yves Dirian, Stefano Foffa +3
Gravitational-wave (GW) detectors can contribute to the measurement of cosmological parameters and to testing the dark-energy sector of alternatives to CDM, by using standard si…
: A New Cosmological Parameter?
Jaiyul Yoo, Ermis Mitsou, Yves Dirian +1
The background photon temperature is one of the fundamental cosmological parameters. Despite its significance, has never been allowed to vary in the data analysis…
General Relativistic Cosmological N-body Simulations I: time integration
David Daverio, Yves Dirian, Ermis Mitsou
This is the first in a series of papers devoted to fully general-relativistic -body simulations applied to late-time cosmology. The purpose of this paper is to present the combi…
