Constraints on charged Symmergent black hole from shadow and lensing
Beyhan Puliçe, Reggie C. Pantig, Ali Övgün +1
In this paper, we report on exact charged black hole solutions in symmergent gravity with Maxwell field. Symmergent gravity induces the gravitational constant , quadratic curvat…
Thin accretion disk images of the black hole in symmergent gravity
İlim İrfan Çimdiker, Ali Övgün, Durmuş Demir
In this paper, we study circular orbits, effective potential, and thin-accretion disk of a black hole in symmergent gravity within the Novikov-Thorne model in a way including the e…
Quasinormal modes and greybody factors of symmergent black hole
Dhruba Jyoti Gogoi, Ali Övgün, Durmuş Demir
Symmergent gravity is an emergent gravity framework in which gravity emerges guided by gauge invariance, accompanied by new particles, and reconciled with quantum fields. In this p…
Probing Geometric Proca in Metric-Palatini Gravity with Black Hole Shadow and Photon Motion
Elham Ghorani, Beyhan Puliçe, Farruh Atamurotov +3
Extended metric-Palatini gravity, quadratic in the antisymmetric part of the affine curvature, is known to lead to the general relativity plus a geometric Proca field. The geometri…
Geometric Proca with Matter in Metric-Palatini Gravity
Durmus Demir, Beyhan Pulice
In the present work, we study linear, torsion-free metric-Palatini gravity, extended by the quadratics of the antisymmetric part of the Ricci tensor and extended also by the presen…
A quantum cosmology approach to cosmic coincidence and inflation
S. Jalalzadeh, A. Mohammadi, D. Demir
This work studies the quantum cosmology of a closed, spatially homogeneous, and isotropic FLRW minisuperspace model with electromagnetic radiation as a matter content. We solve the…
