N-body Simulations of Large-Scale Structure in the Generalized Cubic Covariant Galileon Model
Luís Atayde, Noemi Frusciante, Baojiu Li
We present the first N-body simulations of structure formation in the Generalized Cubic Covariant Galileon (GCCG) model. This theory extends the cubic covariant Galileon through po…

Non-linear Structure Formation in Planck+DESI Favoured Interacting Dark Energy Cosmologies
Yuejia Zhai, Carsten van de Bruck, Eleonora Di Valentino +2
Following our previous work constraining interacting dark energy (IDE) models, which showed their potential to alleviate the Hubble tension, in this work we investigate the non-lin…

Biased tracers, Hybrid Effective Field Theory and Modified Gravity
Guilherme Brando, Baojiu Li, Kazuya Koyama
The modelling of the power spectrum of biased tracers has become a central topic in the analysis of modern cosmological galaxy surveys. Perturbative templates formulated in both Eu…
