Cosmic Expansion in Extended Quasidilaton Massive Gravity
Tina Kahniashvili, Arjun Kar, George Lavrelashvili +3
Quasidilaton massive gravity offers a physically well-defined gravitational theory with non-zero graviton mass. We present the full set of dynamical equations governing the expansi…
Primordial Magnetic Helicity Constraints from WMAP Nine-Year Data
Tina Kahniashvili, Yurii Maravin, George Lavrelashvili +1
If a primordial magnetic field in the universe has non-zero helicity, the violation of parity symmetry results in non-zero correlations between cosmic microwave background temperat…
CMB two- and three-point correlation functions from Alfvén waves
Tina Kahniashvili, George Lavrelashvili
We study the cosmic microwave background (CMB) temperature fluctuations non-gaussianity due to the vector mode perturbations (Alfvén waves) supported by a stochastic cosmological m…
