Hawking and Unruh Radiation Made 'Easy'
Physics Department, Fresno State University
Despite the name, black holes are not black when one considers quantum mechanics. One can take the event horizon as a barrier through which particles can tunnel out from behind the horizon even if they are classically forbidden to do so. These tunneling particles then appear as thermal radiation to an observer outside the event horizon. It is possible flesh out this physical picture with mathematical details and arrive at a simpler and more general derivation of this Hawking radiation from black holes as well as the closely related Unruh radiation seen by an accelerating observer.
