The Black Hole Radiation in Massive Gravity

Understand

We apply the Bogoliubov transformations in order to connect two different vacuums, one~located at past infinity and another located at future infinity around a black hole inside the scenario of the nonlinear theory of massive gravity.

• The presence of the extra degrees of freedom changes the behavior of the logarithmic singularity and, as a consequence, the relation between the two Bogoliubov coefficients.
• This has an effect on the number of particles, or equivalently, on the black hole temperature perceived by observers defining the time arbitrarily.
