Gravitational reheating formulas in oscillating backgrounds

We calculate the reheating temperature in scenarios where heavy particles are gravitationally produced during the oscillations of the inflaton field. We explore two distinct situations: the decay of these particles both during and after the domination of the inflaton's energy density. Subsequently, we determine the respective reheating temperatures. Finally, we find bounds for the maximum reheating temperature.
