TL;DR: In this article, the authors utilize the quasinormal modes of a massless scalar perturbation to probe the Van der Waals-like small and large black holes (SBH/LBH) phase transition of charged topological AdS black holes in four-dimensional massive gravity.

TL;DR: In this article, it was shown that a discontinuity planted into the metric provides an alternative mechanism for the black hole echoes, which correspond to an uneven matter distribution inside the surrounding halo, and that the phenomenon persists even though the discontinuity can be located further away from the horizon with rather insignificant strength.

TL;DR: In this article, it was shown that if there is a single discontinuity in the effective potential, no matter how insignificant it is, the asymptotic behavior of the quasinormal modes will be appreciably modified, even when the discontinuity is located significantly further away from the maximum of the potential and/or the size of the step is arbitrarily small.

TL;DR: In this paper, the authors used the quasinormal modes of a massless scalar perturbation to probe the Van der Waals-like small and large black holes (SBH/LBH) phase transition of charged topological AdS black holes in four-dimensional massive gravity.

TL;DR: In this article, a toy model with axisymmetry, a Kerr black hole enveloped by a thin rotating dark matter shell was devised to reproduce the salient feature of the cuspy shadow.
