Dark Energy with Constant Inertial Mass Density: Updated Constraints and Curvature-Induced Sign Transitions in and
Luis A. Escamilla, Berat Karadavut, Nihan Katırcı
We present updated observational constraints on the simple-gDE model, characterized by a constant inertial mass density (IMD) ,which belongs to the broader g…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
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…
Simple-graduated dark energy and spatial curvature
Giovanni Acquaviva, Ozgur Akarsu, Nihan Katirci +1
In this work, we first discuss the possibility that dark energy models with negative energy density values in the past can alleviate the tension, as well as the discrepancy w…
Rastall gravity extension of the standard CDM model: theoretical features and observational constraints
Ozgur Akarsu, Nihan Katirci, Suresh Kumar +3
We present a detailed investigation of the Rastall gravity extension of the standard CDM model. We review the model for two simultaneous modifications of different nature in the…
