  These lecture notes present an introduction to the fuzzball proposal and
emission from the D1-D5 system which is geared to an audience of graduate
students and others with little background in the subject. The presentation
begins with a discussion of the Penrose process and Hawking radiation. The
fuzzball proposal is then introduced, and the two- and three-charge systems are
reviewed. In the three-charge case details are not discussed. A detailed
discussion of emission calculations for D1-D5-P black holes and for certain
non-extremal fuzzballs from both the gravity and CFT perspectives is included.
We explicitly demonstrate how seemingly different emission processes in
gravity, namely, Hawking radiation and superradiance from D1-D5-P black holes,
and ergoregion emission from certain non-extremal fuzzballs, are only different
manifestations of the same phenomenon in the CFT.
