Description

In this talk ,I will discuss about the process of induced gravity waves due to large scalar fluctuations in the paradigm of quintessential inflation. Numerically solved the Mukhanov-Sasaki equation for different sets of parameters are used to obtain the power spectra. It is been demonstrated that the induced gravity wave signal generated in this framework can falls within the region of the NANOGrav data for the chosen values of model parameters. There is an allowed region of parameter space where the effect shifts to high frequency regime relevant to LISA and other available sensitivities.
