Signatures of kinetic gravity braiding in cosmological probes of the gravitational field

Ahmad Nouri-Zonoz, Farbod Hassani, Julian Adamek +2

We study the observational signatures of kinetic gravity braiding (KGB) models in relativistic cosmological probes constructed along the past light cone. Using the relativistic

PySCo-EFT and ECOSMOG-EFT: a tandem of N-body simulation codes for the Effective Field Theory of Dark Energy

Himanish Ganjoo, Yann Rasera, Emilio Bellini +18

Modified gravity theories constitute viable alternatives to the standard cosmological model for explaining the observed late-time accelerated expansion of the Universe. The Effecti…

Reconstructing the dark energy density in light of DESI BAO observations

Maria Berti, Emilio Bellini, Camille Bonvin +3

In light of the evidence for dynamical dark energy (DE) found from the most recent Dark Energy Spectroscopic Instrument (DESI) baryon acoustic oscillation (BAO) measurements, we pe…
