Quadratic energy-momentum squared gravity: constraints from big bang nucleosynthesis
Ozgur Akarsu, Mariam Bouhmadi-López, Nihan Katirci +1
In this work, we extend the standard cosmological model within the quadratic energy-momentum squared gravity (qEMSG) framework, introducing a nonminimal interaction between the usu…
Equivalence of matter-type modified gravity theories to general relativity with nonminimal matter interaction
Özgür Akarsu, Mariam Bouhmadi-López, Nihan Katırcı +3
In this study, we first establish that gravity models incorporating matter-related terms, such as , , and , into the usu…
Omnipotent dark energy: A phenomenological answer to the Hubble tension
Shahnawaz A. Adil, Ozgur Akarsu, Eleonora Di Valentino +4
This paper introduces the class of omnipotent dark energy (DE) models characterized by nonmonotonic energy densities that are capable of attaining negative values with correspondin…
Model-independent reconstruction of the Interacting Dark Energy Kernel: Binned and Gaussian process
Luis A. Escamilla, Ozgur Akarsu, Eleonora Di Valentino +1
The cosmological dark sector remains an enigma, offering numerous possibilities for exploration. One particularly intriguing option is the (non-minimal) interaction scenario betwee…
Relativistic binary systems in scale-independent energy-momentum squared gravity
Ozgur Akarsu, Elham Nazari, Mahmood Roshan
In this paper, we study the gravitational-wave (GW) radiation and radiative behavior of relativistic binary systems in the scale-independent energy-momentum squared gravity (EMSG).…
