General SIGW source for reheating dynamics

Abstrak
Working in an arbitrary gauge, we derive the source term for scalar-induced gravitational waves (SIGW) valid during a general reheating epoch. Specifically, the dominant energy component is allowed to transition smoothly from an inflaton field to a radiation fluid, possibly via a period of matter domination. Gauge invariance is verified up to second order.
