Hyperbolic Scenario of Accelerating Universe in Modified Gravity

Khan, Raja Azhar Ashraaf; Tiwari, Rishi Kumar; Bharali, Jumi; Bouali, Amine; Yildiz, G. Dilara Açan; Güdekli, Ertan (MDPI, 2023)

Throughout this study, locally rotationally symmetric (LRS) Bianchi type-V space-time is pondered with Tsallis holographic dark energy (THDE) with the Granda–Oliveros (GO) cut-off in the Sáez–Ballester (SB) theory of ...
Optical properties of Euler–Heisenberg black hole surrounded by perfect fluid dark matter

Yıldız, G. Dilara Açan; Ditta, Allah; Ashraf, Asifa; Güdekli, Ertan; Alanazi, Yousef Mohammed; Reyimberganov, Anvar (Elsevier B.V., 2024)

This work explores the phenomenon of plasma lensing in weak plasma fields around Euler–Heisenberg black holes submerged in perfect fluid dark matter. For both uniform and non-uniform plasma environments, the deflection ...
Testing of Kerr black hole with quintessential dark energy through observational data by using quasi-periodic oscillations

Liu, Yong; Mustafa G.; Maurya S.K.; Yıldız, G.D. Açan; Güdekli, Ertan (Elsevier B.V., 2023)

A viable method to examine the wide range of intriguing phenomena that occur in a strong gravity regime is the study of the quasi-periodic oscillations (QPOs) of X-ray flux seen in stellar-mass black hole (BH) binaries. ...
