Ringdown signatures in the Ernst-Wild geometry: modeling Kerr black holes immersed in a magnetic field
Kate J. Taylor, Adam Ritz
We analyze the quasinormal mode spectrum for Kerr black holes surrounded by an asymptotically uniform magnetic field, modeled with the Ernst-Wild geometry. A perturbative expansion…

Null orbits and shadows in the Ernst-Wild geometry: insights for black holes immersed in a magnetic field
Kate J. Taylor, Adam Ritz
We investigate the null geodesics, in particular the stable and unstable light rings and shadows, of a Kerr-Newman black hole immersed in an asymptotically uniform magnetic field a…
