Threshold Tails of Black hole Differential Observables
Vedant Subhash
We study how first-order differential observables affect the zero-frequency behavior of black-hole wave equations. Quasinormal modes and late-time tails do not always change in the…

Spectral Invariance for Black-Hole Differential Observables
Vedant Subhash
We study first-order differential quantities built from solutions of second-order black-hole wave equations. These quantities can satisfy new differential equations that contain ex…

Varying conical defects in Rotating Wormholes
Vedant Subhash
We study a rotating wormhole whose conical deficit varies along the proper radial direction. The varying deficit produces a mixed Einstein equation and an additional near-axis stre…
