Phys. Rev. D 76, 104042 (2007) [6 pages]Hawking temperature of expanding cosmological black holesReceived 1 July 2007; published 27 November 2007 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 mH of the hole is T=(8πmH(t))-1. This expression holds for comoving black holes and agrees with a recent proposal by Saida, Harada, and Maeda. © 2007 The American Physical Society URL:
