Scalar Perturbations of a Single-Horizon Regular Black Hole
Ramin G. Daghigh, Michael D. Green, Jodin C. Morey +1
We investigate the massless scalar field perturbations, including the quasinormal mode spectrum and the ringdown waveform, of a regular black hole spacetime that was derived via th…

Significance of Black Hole Quasinormal Modes: A Closer Look
Ramin G. Daghigh, Michael D. Green, Jodin C. Morey
It is known that approximating the Regge-Wheeler Potential with step functions significantly modifies the Schwarzschild black hole quasinormal mode spectrum. Surprisingly, this cha…
