Quasiperiodic oscillations, weak field lensing and shadow cast around black holes in Symmergent gravity

Understand

In this work, we perform a systematic study of the symmergent gravity in a black hole environment.

• The symmergent gravity, an emergent gravity model in which gravity emerges in a way restoring the gauge symmetries and stabilizing the Higgs boson mass, possesses a quadratic-curvature term with a loop-induced coupling proportional to the boson-fermion number difference.
• We investigated boson-fermion number difference and black hole parameters in symmergent gravity by utilizing the values of various observables.
• In this regard, we investigated particle dynamics and obtained Keplerian frequencies describing the harmonic oscillations.
