Overview

Randomized trial explores gravitational phenomena in black holes, highlighting new implications for gravity theories.

Key Points

  • This work aims to explore the gravitational effects of a new black hole solution with quantum corrections to General Relativity.
  • Analyzed horizon structure by focusing on event and Cauchy horizons.
  • Examined quasinormal modes considering various perturbations and computed time domains.
  • Investigated gravitational lensing in weak and strong deflection limits using observational data.
  • Identified the stability of the photon sphere and its effect on black hole shadows.
  • Provided constraints on parameter ξ using Solar System measurements and light bending.
  • Demonstrated the significance of quasinormal modes in understanding black hole dynamics.
