Surface-gravity waves in shallow water can be configured with central and graded drainage to analogize regular black holes and mimickers, enabling lab study of their instabilities.
First experimental emulation of fermionic wave packet dynamics in Lorentzian AdS2 spacetime using photonic waveguide arrays, showing mass-independent geodesic oscillations and curvature-dependent Zitterbewegung.
Static Love numbers for bosonic and fermionic fields around acoustic black holes follow universal power laws for fermions and exhibit logarithmic structures for bosons in lower dimensions.
Pseudospectrum of Schwarzschild QNMs shows stability of the fundamental mode to infrared perturbations respecting asymptotics and instability of overtones to ultraviolet high-frequency perturbations.
Multi-component galactic potentials strongly shift critical points, shock parameters, and acoustic surface gravity in transonic accretion flows around non-rotating pseudo-Schwarzschild black holes under the vertical equilibrium model.
