Cosmological Signatures of Curvature-Coupled Dark Energy
Abdolali Banihashemi, Farbod Hassani, Alessandro Casalino +2
We study a curvature-coupled dark energy model that can modify cosmological evolution both before recombination and during the late-time accelerated era. The model belongs to the c…
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 …
KGB-evolution: a relativistic -body code for kinetic gravity braiding models
Ahmad Nouri-Zonoz, Farbod Hassani, Emilio Bellini +1
We present KGB-evolution, a relativistic -body simulation code that extends the -evolution code by incorporating an effective field theory parameterization of kinetic gravity…
Matter Power Spectra in Modified Gravity: A Comparative Study of Approximations and -Body Simulations
Benjamin Bose, Ashim Sen Gupta, Bartolomeo Fiorini +9
Testing gravity and the concordance model of cosmology, CDM, at large scales is a key goal of this decade's largest galaxy surveys. Here we present a comparative study of dark m…
-elator: emulating clustering effects of the -essence dark energy
A. R. Nouri-Zonoz, F. Hassani, M. Kunz
We build an emulator based on the polynomial chaos expansion (PCE) technique to efficiently model the non-linear effects associated with the clustering of the -essence dark ener…
Environmental cosmic acceleration from a phase transition in the dark sector
Øyvind Christiansen, Farbod Hassani, David F. Mota
A new degravitation mechanism within the framework of scalar tensor gravity is postulated and included by prescription. The mechanism eliminates all constant contributions from the…
