New multiprobe analysis of modified gravity and evolving dark energy
Zhiyu Lu, Théo Simon
We study the parametrization of the dark energy (DE) equation of state, with and without the effective field theory of dark energy (EFTofDE) framework to describe t…
Impact of ACT DR6 and DESI DR2 for Early Dark Energy and the Hubble tension
Vivian Poulin, Tristan L. Smith, Rodrigo Calderón +1
The data release six of the Atacama Cosmology Telescope (ACT DR6) and the second data release from the Dark Energy Spectroscopic Instrument (DESI DR2) recently became available. In…
Primordial Features in light of the Effective Field Theory of Large Scale Structure
Rodrigo Calderon, Théo Simon, Arman Shafieloo +1
While the simplest inflationary models predict a power-law form of the primordial power spectrum (PPS), various UV complete scenarios predict features on top of the standard power…
Self-interacting neutrinos in light of recent CMB and LSS data
Adèle Poudou, Théo Simon, Thomas Montandon +2
We update constraints on a simple model of self-interacting neutrinos involving a heavy scalar mediator with universal flavor coupling. According to past literature, such a model i…
Preference for evolving dark energy in light of the galaxy bispectrum
Zhiyu Lu, Théo Simon, Pierre Zhang
We analyse pre-DESI clustering data using a dark energy equation of state parametrised by , finding a preference for evolving dark energy over the cos…
Towards alleviating the and tensions with Early Dark Energy - Dark Matter drag
Théo Simon, Tal Adi, José Luis Bernal +3
Early dark energy, an additional component of dark energy active in the decade of redshift before recombination, has emerged as one of the most effective models at reducing the $H_…
