Comment on the ``Invariance of the Tunneling Method for Dynamical Black Holes''

TL;DR

This paper critiques a recent claim about the invariance of the tunneling method for dynamical black holes, reaffirming the author's previous results and identifying errors in the referenced work.

Contribution

The paper provides a correction to recent claims about the tunneling method, reaffirming the author's earlier findings and clarifying the correct approach.

Findings

Confirmed the author's previous calculation of Hawking radiation.

Identified errors in the recent paper by Di Criscienzo et al.

Reaffirmed the invariance of the tunneling method for dynamical black holes.

Abstract

In the recent paper arXiv:0906.1725 it has been guessed that a ``correct'' treatment of the semi-classical tunneling based on the Hamilton-Jacobi equation gives the standard Hawking formula, contrary to was asserted in my previous paper arXiv:0904.4572. Here I confirm my calculation showing where the article of Di Criscienzo et al. is wrong.
