Abstract
We study the Hawking radiation of the Kerr-Newman-dS black hole on its event horizon and cosmological horizon from the tunneling approach of Parikh and Wilczek. In order to eliminate the motion on the rotating degree of freedom of a tunneling particle coming from the rotation of the Kerr-Newman-dS black hole, we choose a reference system that is co-rotating with the black hole horizon. Using such a method, we can derive the Hawking temperature of a general rotating black hole from the tunneling approach clearly. Then, to use the general result to the Kerr-Newman-dS case, we reproduce the Hawking temperatures of the Kerr-Newman-dS black hole on its event horizon and cosmological horizon from the tunneling approach.
