Bouncing universe scenarios in an extended gravitational framework involving curvature-matter coupling
Zubair M.; Muneerq, Quratulien; Waheed, Saira; Yıldız, G. Dilara Açan; Güdekli, Ertan (Elsevier B.V., 2024)Exploration of bouncing cosmic models in modified theories has gained much popularity in modern cosmology. This paper explores the Lagrangian function of a new theory namely F(R,Lm,T) framework by taking four renowned ... -
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 ... -
Orbital motion, epicyclic oscillations, and collision of particles around conformally coupled charged black hole
Mustafa G.; Açan Yıldız, Gizem Dilara; Javed, Faisal; Maurya, S. K.; Güdekli, Ertan; Atamurotov, Farruh (Elsevier Ltd., 2024)The orbital and oscillatory motion of test particles around a non-rotating, conformally coupled charged black hole with scalar hair is studied in this work. The impact of the black hole parameters on particle motion is ... -
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. ... -
Thermodynamics of the most generalized form of holographic dark energy and some particular cases with corrected entropies
Saha, Sanghati; Güdekli, Ertan; Chattopadhyay, Surajit; Açan Yıldız, Gizem Dilara (ELSEVIER, 2025)A four-parameter generalized entropy has recently been developed based on the generalized cut-off of holographic dark energy (HDE) formalism. It reduces to various known entropies for appropriate parameter limits, as shown ...
