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…
