Quartic Scalar Clouds on Fixed Kerr Backgrounds
Hendrik Mennenga
The paper investigates stationary nonlinear scalar field configurations (Q‑clouds) on fixed Kerr and Schwarzschild black hole backgrounds, analyzing quartic and axion‑inspired pote…
Constrained thermodynamics and geodesic observables of an effective non-commutative Kerr-like black hole
H. Hassanabadi, L. A. López, N. Bretón +2
The paper analyzes how a non‑commutative deformation alters the horizon structure, thermodynamic properties, and geodesic observables of a Kerr‑like black hole, including its shado…
A Bound on the Dynamical Love Number
Alex Kehagias, Antonio Riotto
The paper derives a theoretical bound on the frequency dependence of the tidal deformability (Love number) of compact objects such as neutron stars and black holes, using the Schwa…
Static topological dilatonic black hole with multiple horizons and its thermodynamics
M. M. Stetsko
The paper presents a static topological charged black hole solution in Einstein‑dilaton gravity with a nonlinear electromagnetic field, showing that the nonlinear extension can pro…
Analytic backreaction of a scalar wig on a Schwarzschild black hole
Marco de Cesare, Manuel Del Piano, Carlos A. R. Herdeiro
The paper analytically computes how a massive scalar quasi‑bound state backreacts on a Schwarzschild black hole, deriving metric perturbations, horizon evolution, and the scalar’s…
Kerr black holes without primary hairs
J Ovalle
The paper introduces a family of regular, axisymmetric black hole solutions fully characterized by mass and spin parameters that retain the Kerr event horizon, smoothly interpolati…
