Description
I will discuss the implementation of K-mouflage models
of Modified Gravity in the EFTCAMB solver and its application to
constraining K-mouflage theories using Planck data. I will show that,
since K-mouflage presents a non-trivial expansion history at high-redshift,
interesting bounds on relevant parameters can already be placed by looking at
primordial CMB spectra. Finally, I will briefly discuss CMB-galaxy cross-correlation
in K-mouflage scenarios, showing that also in this case an interesting phenomenology
arises, due to the evolution of the growth factor in the matter dominated regime.
