Conserved Gravitational Charges as Curvature Fluxes
Emel Altas, Bayram Tekin
Conserved gravitational charges are commonly expressed as surface integrals of the metric perturbation and its first derivatives. We show that, in the usual asymptotically AdS and…

Static Tidal Perturbations of Relativistic Stars: Corrected Center Expansion and Love Numbers-I
Emel Altas, Ercan Kilicarslan, Onur Oktay +1
We revisit static tidal perturbations of relativistic stars with emphasis on two technical issues in the standard quadrupolar formulation. First, we derive the regular-center Frobe…

Geometry is Wavy: Curvature Wave Equations for Generic Affine Connections
Emel Altas, Bayram Tekin
Geometry is wavy: even at the purely geometric level (no particular theory chosen), curvature satisfies a covariant quasilinear wave equation. In Riemannian geometry equipped with…
