Spindle black holes and mass-deformed ABJM

Abstract

By extending the method developed by Arav, Gauntlett, Roberts and Rosen, we construct supersymmetric $AdS_2\times{\Sigma}$ solutions of gauged $\mathcal{N}=8$ supergravity which are asymptotic to the $SU(3)\times{U}(1)$-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 $AdS_2\times{\Sigma}$ horizon.
