Exact gravitational lensing by cosmic strings with junctions
Teruaki Suyama
We point out that the results by Brandenberger et al. in Phys.Rev.D77:083502(2008) that the geometry around the straight cosmic strings with stationary junctions is flat to linear…
Primordial Curvature Fluctuation and Its Non-Gaussianity in Models with Modulated Reheating
Kazuhide Ichikawa, Teruaki Suyama, Tomo Takahashi +1
We investigate non-Gaussianity in the modulated reheating scenario where fluctuations of the decay rate of the inflaton generate adiabatic perturbations, paying particular attentio…
Non-Gaussianity, Spectral Index and Tensor Modes in Mixed Inflaton and Curvaton Models
Kazuhide Ichikawa, Teruaki Suyama, Tomo Takahashi +1
We study non-Gaussianity, the spectral index of primordial scalar fluctuations and tensor modes in models where fluctuations from the inflaton and the curvaton can both contribute…
Non-Gaussianity in the modulated reheating scenario
Teruaki Suyama, Masahide Yamaguchi
We investigate the non-Gaussianity of primordial curvature perturbation in the modulated reheating scenario where the primordial perturbation is generated due to the spacial fluctu…
