Description

It has been found that squeezed tensor non-Gaussianities can induce anisotropies in the Stochastic Gravitational Wave Background (SGWB). One of the models predicting enhanced non-Gaussianities at the squeezed limit is inflation with non-Bunch-Davies initial states. In this talk, we will show that the non-Bunch-Davies effects can potentially enhance the SGWB anisotropies.
