Spindle black holes and mass-deformed ABJM

Abstract

By extending the method developed by Arav, Gauntlett, Roberts and Rosen, we construct supersymmetric AdS(2) x Sigma solutions of gauged N = 8 supergravity which are asymptotic to the SU(3) x U(1)-invariant Warner fixed point, where Sigma is a spindle. The Warner fixed point is dual to the mass-deformed ABJM theory. The solutions are in the anti-twist class. We numerically calculate the Bekenstein-Hawking entropy of the presumed black holes with the AdS(2) x Sigma horizon.
