Hawking radiation, by definition only needs an event horizon. that can be any kind of event horizon and we already know those can be produced by: massive gravity (black hole) massive acceleration (the edge of our universe) warping of space due to theoretical unknown matter (wormholes) you can also create virtual event horizons for waves of any kind by creating the correct conditions. like any model, some attributes are applicable to a spacial event horizon, and some are not. you don’t need gravity for hawking radiation.
