Implication

Randomized trial investigates dynamics and emission rates from a deformed AdS black hole with global monopole and quintessence, highlighting significant findings.

Key Points

  • This research explores the dynamics of a deformed anti-de Sitter black hole influenced by a global monopole and quintessence, focusing on geodesics and emission rates.
  • Analyzed geodesic motion of null and timelike particles to define the photon sphere.
  • Derived perturbative potentials for scalar and electromagnetic fields using the third-order WKB method.
  • Computed emission rates within the AdS thermodynamic framework, incorporating the Hawking–Page transition.
  • The angular shadow radius is established as a key observable for finite-distance observers.
  • Emission rates are reduced by the global monopole, deformation, and quintessence parameters, while increased by the control parameter.
  • Quasinormal mode frequencies align closely with about one percent agreement between ringdown and unstable circular null orbit frequencies.
