Shankaranarayanan, IISER Thiruvananthapuram Abstract Type : Poster Abstract Category : General Relativity and Cosmology Abstract : We consider a modified gravity model of the form f(R,\phi)=Re^{h(\phi)R}, where \phi is a non-interacting massive scalar field. This model leads to an exact solution, which leads to inflation with exit. We show that the exit depends on the initial velocity of the scalar field and hence leads to a viable inflationary model. We proceed to compare the power spectrum of this model with observational data to constrain the parameter space. |
