Greybody Factors and Charges in Kerr/CFT

Understand

We compute greybody factors for near extreme Kerr black holes in D=4 and D=5.

• In D=4 we include four charges so that our solutions can be continuously deformed to the BPS limit.
• In D=5 we include two independent angular momenta so Left-Right symmetry is incorporated.
• We discuss the CFT interpretation of our emission amplitudes, including the overall frequency dependence and the dependence on all black hole parameters.
