Abstract

In the context of a debate on the correct expression of the Hawking temperature of a cosmological black hole, we show that the correct expression in terms of the Hawking-Hayward quasilocal energy m_H of the hole is T=(8\ensuremathπm_H(t))^\ensuremath-1. This expression holds for comoving black holes and agrees with a recent proposal by Saida, Harada, and Maeda.
