abstract
We investigate the evolution of small perturbations around black strings and branes which are low energy solutions of string theory. For simplicity we focus attention on the zero charge case and show that there are unstable modes for a range of time frequency and wavelength in the extra $10-D$ dimensions. These perturbations can be stabililized if the extra dimensions are compactified to a scale smaller than the minimum wavelength for which instability occurs and thus will not affect large astrophysical black holes in four dimensions. We comment on the implications of this result for the Cosmic Censorship Hypothesis.

A warped 5D geometry with hidden-sector accretion produces growing Schwarzschild/Vaidya black-hole seeds on our brane via a common horizon intersection.
Exact solutions in Einstein-SU(2) sigma model yield black holes and branes with bumpy horizons stabilized by integer vorticity of superfluid pions.
An MST-type analytic solution for the reduced confluent Heun equation of 5d Schwarzschild-Tangherlini scalar perturbations is constructed and its angular-momentum parameter matches the Seiberg-Witten value.
Thermodynamic quantities for black p-branes in arbitrary dimensions can be derived without constructing solutions by generalizing a previous method, including cases with general scalar cosets.
Quantum backreaction generates horizons that cloak the Choptuik naked singularity, reducing its predictability violation to the standard black hole evaporation problem.
Instanton condensation in the matrix model for the BPS index reveals a new instability and dominant phase for small black holes, connected to partial deconfinement.
Semiclassical one-loop analysis of solvable near-critical collapse solutions shows quantum corrections selecting a Boulware-like state and producing a growing mode that yields a finite mass gap and a transition to Type I behavior, enforcing weak cosmic censorship.
Simulations of 5D black string instability in Einstein-Gauss-Bonnet gravity find that positive Gauss-Bonnet coupling caps curvature growth inside EFT validity, unlike negative coupling.
Semi-holographic systems with perturbative and holographic sectors exhibit prethermal time crystals through dissipationless modes in hydrodynamic channels plus short-wavelength instabilities that produce inhomogeneities over a wide temperature range.
New exact non-SUSY black brane solutions in 10D heterotic supergravity with two gauge charges show a spontaneous symmetry breaking and dynamical instability at low temperature that predicts additional black hole solutions.
Kerr-Schild double copy of the RSII black string gives a holographic-coordinate-independent sourceless single-copy gauge field and a zeroth copy with warp-induced mass m²=12/l², while an alternative split is inequivalent.
New exact charged black-string solution in Einstein gravity coupled to Kiselev quintessence plus string cloud, with horizon, curvature, energy-condition, thermodynamic, and null-geodesic analysis.
Theoretical investigation of black hole fragmentation possibilities beyond standard GR constraints, with relevance to primordial black holes and mergers.
Quasinormal modes are eigenmodes of dissipative gravitational systems whose spectra encode near-equilibrium transport coefficients in dual quantum field theories and enable tests of general relativity through gravitational wave observations.
This review surveys calculations and interpretations of quasinormal modes for black holes in astrophysics, higher dimensions, and holographic duals without presenting new results.
