Euclid preparation. Review of forecast constraints on dark energy and modified gravity
Euclid Collaboration, N. Frusciante, M. Martinelli +326
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
Cosmological Tensions and the Transitional Planck Mass Model
Joshua A Kable, Giampaolo Benevento, Graeme E Addison +1
In this followup analysis, we update previous constraints on the Transitional Planck Mass (TPM) modified gravity model using the latest version of EFTCAMB and provide new constrain…
Euclid: Constraining linearly scale-independent modifications of gravity with the spectroscopic and photometric primary probes
N. Frusciante, F. Pace, V. F. Cardone +127
The future Euclid space satellite mission will offer an invaluable opportunity to constrain modifications to Einstein's general relativity at cosmic scales. We focus on modified gr…
An exploration of an early gravity transition in light of cosmological tensions
Giampaolo Benevento, Joshua A. Kable, Graeme E. Addison +1
We study a step-like transition in the value of the effective Planck mass (or effective gravitational constant) on cosmological scales prior to recombination. We employ CMB, BAO, a…
Probing Modified Gravity with Integrated Sachs-Wolfe CMB and Galaxy Cross-correlations
Joshua A. Kable, Giampaolo Benevento, Noemi Frusciante +2
We use the cross-correlation power spectrum of the integrated Sachs-Wolfe (ISW) effect in the cosmic microwave background (CMB) temperature anisotropy and galaxy fluctuations to pr…
Can Late Dark Energy Transitions Raise the Hubble constant?
Giampaolo Benevento, Wayne Hu, Marco Raveri
Late times dark energy transitions at redshifts can raise the predicted value of the Hubble constant to the SH0ES value, (km s Mpc or mor…
Acoustic Dark Energy: Potential Conversion of the Hubble Tension
Meng-Xiang Lin, Giampaolo Benevento, Wayne Hu +1
We discuss the ability of a dark fluid becoming relevant around the time of matter radiation equality to significantly relieve the tension between local measurements of the Hubble…
Cosmological constraints and phenomenology of a beyond-Horndeski model
Simone Peirone, Giampaolo Benevento, Noemi Frusciante +1
We study observational constraints on a specific dark energy model in the framework of Gleyzes-Langlois-Piazza-Vernizzi theories, which extends the Galileon ghost condensate (GGC)…
Cosmological data favor Galileon ghost condensate over CDM
Simone Peirone, Giampaolo Benevento, Noemi Frusciante +1
We place observational constraints on the Galileon ghost condensate model, a dark energy proposal in cubic-order Horndeski theories consistent with the gravitational-wave event GW1…
K-mouflage Imprints on Cosmological Observables and Data Constraints
Giampaolo Benevento, Marco Raveri, Andrei Lazanu +4
We investigate cosmological constraints on K-mouflage models of modified gravity. We consider two scenarios: one where the background evolution is free to deviate from CDM (K-mo…
