MGCAMB with massive neutrinos and dynamical dark energy

3 code implementations17 Jan 2019 Alex Zucca, Levon Pogosian, Alessandra Silvestri, Gong-Bo Zhao

To illustrate the capabilities of the code, we present joint constraints on the modified growth, massive neutrinos and the dark energy equation of state from the latest cosmological observations, including the recent galaxy counts and weak lensing measurements from the Dark Energy Survey, and find a good consistency with the {\Lambda}CDM model.
