Analytic formula for quasinormal modes in the near-extreme Kerr-Newman-de Sitter spacetime governed by a non-Pöschl-Teller potential
M. S. Churilova, R. A. Konoplya, A. Zhidenko
Quasinormal modes of scalar, electromagnetic, and gravitational fields in the extreme Schwarzschild-de Sitter background are known to be expressed in analytic form as eigenvalues o…

Wormholes without exotic matter: quasinormal modes, echoes and shadows
M. S. Churilova, R. A. Konoplya, Z. Stuchlik +1
An analytical solution representing traversable asymptotically flat and symmetric wormholes was obtained without adding exotic matter in two different theories independently: in th…
