The Kerr-Newman metric describes a very special rotating, charged mass and is the most
general of the asymptotically flat stationary'black hole'solutions to the Einstein-Maxwell …

We introduce a systematic and direct procedure to generate hairy rotating black holes by
deforming a spherically symmetric seed solution. We develop our analysis in the context of …

We give a detailed review of construction of conserved quantities in extended theories of
gravity for asymptotically maximally symmetric spacetimes and carry out explicit …

A bstract We consider black holes generically sourced by quantum matter described by
regular wavefunctions. This allows for integrable effective energy densities and the removal …

Current observations present unprecedented opportunities to probe the true nature of black
holes, which must harbor new physics beyond General Relativity to provide singularity-free …

We present analytic stationary and axially symmetric black hole solutions to the
semiclassical Einstein equations that are sourced by the trace anomaly. We also find …

We interpret the cosmological constant as the energy of the vacuum, and under a minimum
amount of assumptions, we show that it is deformed in the vicinity of a black hole. This leads …

Static and stationary regular black holes are examined under a minimal set of requirements
consisting of (i) the existence of a well defined event horizon and (ii) the weak energy …

Black hole solutions in general relativity come with pathologies such as singularity and mass
inflation instability, which are believed to be cured by a yet-to-be-found quantum theory of …

A bstract We propose seven criteria to single out physically reasonable non-singular black-
hole models and adopt them to four different spherically symmetric models with a regular …
