Implication

Develops a geodesic-optics model to analyze quasinormal modes and binding energy in black holes, suggesting new insights into their dynamics.

Key Points

  • The aim is to analyze quasinormal ringing, shadows, lensing, grey-body factors, and binding energy in regular black holes using phantom Dirac-Born-Infeld gravity.
  • Developed a geodesic-optics treatment for quasinormal modes and other phenomena
  • Examined the stable conditions for photon orbits and circular motion for massive particles
  • Derived exact expressions for binding energy and angular momentum metrics.
  • Eikonal quasinormal modes and observables are governed by a single function of the core-size parameter.
  • The innermost stable circular orbit (ISCO) condition shows decreased binding efficiency as the core grows.
  • Illustrative plots depict geodesic invariants and corresponding grey-body profiles.
