 lack Holes - Fred Alford (Imperial College)

DESCRIPTION:In the first part of this talk\, we will (briefly) derive the 
 original calculation by Hawking in 1974 to determine the radiation given o
 ff by a black hole\, giving the result in the form of an integral of a cla
 ssical solution to the linear wave equation.\nIn the second part of the ta
 lk\, we will take this integral as a starting point\, and rigorously calcu
 late the radiation given off by a forming spherically symmetric\, charged 
 black hole. We will show that for late times in its formation\, the radiat
 ion given off approaches the limit predicted by Hawking\, including the ex
 tremal case. We will also calculate a bound on the rate at which this limi
 t is approached.
