Quasinormal frequencies for a black hole in a bumblebee gravity

Understand

After recent observational events like the LIGO-Virgo detections of gravitational waves and the shadow image of M87* supermassive black hole by Event Horizon Telescope (EHT), the theoretical study of black holes was significantly improved.

• Quantities as quasinormal frequencies, shadows, and light deflection become more important to analyze black hole models.
• In this context, an interesting scenario to study is a black hole in the bumblebee gravity.
• The bumblebee vector field imposes a spontaneous symmetry breaking that allows the field to acquire a vacuum expectation value that generates Lorentz-Violating (LV) into the black hole.
