Combining chirp mass, luminosity distance and sky localisation from gravitational wave events to detect the cosmic dipole
N. Grimm, M. Pijnenburg, S. Mastrogiovanni +3
A key test of the isotropy of the Universe on large scales consists in comparing the dipole in the Cosmic Microwave Background (CMB) temperature with the dipole in the distribution…
Detection and estimation of the cosmic dipole with the Einstein Telescope and Cosmic Explorer
S. Mastrogiovanni, C. Bonvin, G. Cusin +1
One of the open issues of the standard cosmological model is the value of the cosmic dipole measured from the Cosmic Microwave Background (CMB), as well as from the number count of…
Cosmology with LIGO/Virgo dark sirens: Hubble parameter and modified gravitational wave propagation
Andreas Finke, Stefano Foffa, Francesco Iacovelli +2
We present a detailed study of the methodology for correlating `dark sirens' (compact binaries coalescences without electromagnetic counterpart) with galaxy catalogs. We propose se…
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…
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…
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…
The gravitational-wave luminosity distance in modified gravity theories
Enis Belgacem, Yves Dirian, Stefano Foffa +1
In modified gravity the propagation of gravitational waves (GWs) is in general different from that in general relativity. As a result, the luminosity distance for GWs can differ fr…
Non-local gravity and comparison with observational datasets. II. Updated results and Bayesian model comparison with CDM
Yves Dirian, Stefano Foffa, Martin Kunz +2
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…
Non-local gravity and comparison with observational datasets
Yves Dirian, Stefano Foffa, Martin Kunz +2
We study the cosmological predictions of two recently proposed non-local modifications of General Relativity. Both models have the same number of parameters as CDM, with a mass…
Cosmological perturbations and structure formation in nonlocal infrared modifications of general relativity
Yves Dirian, Stefano Foffa, Nima Khosravi +2
We study the cosmological consequences of a recently proposed nonlocal modification of general relativity, obtained by adding a term to the Einstein-Hilbert acti…
