Hawking radiation in a charged, cosmological black hole

We study the effective temperature, as a rate of gravitational redshift, of the Hawking modes perceived by a radially free falling observer at an arbitrary location in a Reissner-Nordstr\"om-(Anti-)de Sitter (RN(A)dS) spacetime. Observers of both positive and negative specific energies have been taken into account. Particular emphasis is on the behaviour of the modes at the inner horizon, and therein on the validity of the strong cosmic censorship conjecture across the physically permissible parameter space of the RNdS metric. Lastly, the behavior of the adiabatic control function has been analysed over the position space of the observer to determine the regimes where the effective temperature function yields a Planckian spectrum of thermal radiation.
