Introduction to quantum field theory, momentum space Feynman rules (supplement). Mostly basic perturbation theory with scalars and no gauge symmetry. Main source: Peskin and Schroeder.
Hawking radiation on a Vaidya spacetime. This derivation does not discuss the universality of the radiation spectrum -- it just provides a specific example. Source: this paper; I just wrote out the calculations in some more detail.
