Description
I will discuss cosmological aspects of massive gravity theories
such as graviton mass signatures on the cosmic microwave background (CMB)
temperature and polarization anisotropies.
In particular, I will refer to a reduction of large scale power of the
CMB temperature anisotropies that might be due to the non-zero graviton
mass.
In the second part of my talk I will analyze in detail consequences of
extended quasidilaton theory and derive constraints on parameters of this
theory.
