Effective field theory of statistical anisotropies for primordial bispectrum and gravitational waves
Tahereh Rostami, Asieh Karami, Hassan Firouzjahi
We present the effective field theory studies of primordial statistical anisotropies in models of anisotropic inflation. The general action in unitary gauge is presented to calcula…

Primordial inhomogeneities from massive defects during inflation
Hassan Firouzjahi, Asieh Karami, Tahereh Rostami
We consider the imprints of local massive defects, such as a black hole or a massive monopole, during inflation. The massive defect breaks the background homogeneity. We consider t…
