Electromagnetic Response of Stochastic High-Frequency Gravitational Waves from Inflaton Decay

This paper concerns the production of a high-frequency stochastic gravitational wave background (SGWB) generated during the reheating epoch through gravitational decays of the inflaton field. Our analysis focuses on scenarios in which the inflaton predominantly decays into pairs of vector particles....
