Cosmological constraints on a decomposed Chaplygin gas
Yuting Wang, David Wands, Lixin Xu +2
Any unified dark matter cosmology can be decomposed into dark matter interacting with vacuum energy, without introducing any additional degrees of freedom. We present observational…
Practical solutions for perturbed f(R) gravity
Alireza Hojjati, Levon Pogosian, Alessandra Silvestri +1
We examine the accuracy of the quasi-static approximation and a parametric form commonly employed for evolving linear perturbations in f(R) gravity theories and placing cosmologica…
Testing gravity with CAMB and CosmoMC
Alireza Hojjati, Levon Pogosian, Gong-Bo Zhao
We introduce a patch to the commonly used public codes CAMB and CosmoMC that allows the user to implement a general modification of the equations describing the growth of cosmologi…
