Hawking radiation as perceived by different observers: an analytic expression for the effective-temperature function

Given a field vacuum state in a black hole spacetime, this state can be analysed in terms of how it is perceived (in terms of particle content) by different observers. This can be done by means of the effective-temperature function introduced by Barcelo et al (2011 Phys. Rev. D 83 041501). In Barbad...

We give a clear physical interpretation of the quantities appearing in the expression, and illustrate its potentiality with a few examples.
