An efficient one-loop EFTofLSS framework for Vainshtein-screened Horndeski gravity
Stan Verhoeve, Dani de Boe, Gen Ye +1
The authors extend the PyBird code to compute one-loop matter power spectra for Vainshtein‑screened Horndeski and nDGP gravity using a direct ODE approach for time‑dependent kernel…
-EFTCAMB: A Cobaya-Integrated, Python-Wrapped Extension of EFTCAMB for Covariant Horndeski Gravity
Gen Ye, Shijie Lin, Jiaming Pan +6
We present , the official successor to . The original is designed as a consistent and numerically stable implemen…
Nonlinear Scales in Luminal Horndeski -- I. Halo mass function and power spectrum boost in models with Vainshtein screening
Dani de Boe, Mattia Pantiri, Gen Ye +1
We investigate nonlinear structure formation in Horndeski gravity with a luminal gravitational wave speed () using the spherical collapse model incorporating Vainshtein sc…
A General Model for Dark Energy Crossing the Phantom Divide
Zhibang Yao, Gen Ye, Alessandra Silvestri
Within the framework of spatially covariant theories, we propose a general model for dark energy (DE) in which the cosmological background and perturbations are independently contr…
Hints of Nonminimally Coupled Gravity in DESI 2024 Baryon Acoustic Oscillation Measurements
Gen Ye, Matteo Martinelli, Bin Hu +1
The cosmic microwave background (CMB) and baryon acoustic oscillations (BAO) are two of the most robust observations in cosmology. The recent BAO measurements from the DESI collabo…
A model-independent reconstruction of the matter power spectrum
Gen Ye, Jun-Qian Jiang, Alessandra Silvestri
We propose a new model-independent reconstruction method for the matter power spectrum based on its time dependence and a combination of observations from different redshifts. The…
