Spindle black holes and mass-deformed ABJM

By extending the method developed by Arav, Gauntlett, Roberts and Rosen, we construct supersymmetric $Ad{S}_2\times \mathrm{\Sigma }$ solutions of gauged $\mathcal{N}=8$ supergravity which are asymptotic to the $SU(3)\times U(1)$-invariant Warner fixed point, where $\mathrm{\Sigma }$ 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 $Ad{S}_2\times \mathrm{\Sigma }$ horizon.
