SUMMARY:Stirring a black hole - J. Markeviciute
DTSTART:20170224T130000Z

CONTACT:Christopher Moore
DESCRIPTION:In this talk I will present novel solutions in global AdS4\, w
 hich are constructed by turning on a dipolar differential rotation at the 
 conformal boundary. We find two different geometries: a horizonless AdS so
 liton\, and a rotating black hole with zero net angular momentum. The larg
 e black hole branch has an extended hourglass shape\, and exists up to a m
 aximum amplitude of the boundary profile. At this value\, there is an ergo
 region attached to the boundary\, signalling superradiant instability. I w
 ill discuss the phase diagram and implications for weak cosmic censorship.
