Relaxing cosmological tensions with a sign switching cosmological constant: Improved results with Planck, BAO, and Pantheon data
Ozgur Akarsu, Suresh Kumar, Emre Ozulker +2
We present a further observational analysis of the CDM model proposed in Akarsu et al. [Phys. Rev. D 104, 123512 (2021)]. This model is based on the recent conjecture su…
Weak field and slow motion limits in energy-momentum powered gravity
Ozgur Akarsu, A. Kazim Camlibel, Nihan Katirci +2
We explore the weak field and slow motion limits, Newtonian and Post-Newtonian limits, of the energy-momentum powered gravity (EMPG), viz., the energy-momentum squared gravity (EMS…
Inevitable manifestation of wiggles in the expansion of the late Universe
Ozgur Akarsu, Eoin O. Colgain, Emre Ozulker +2
Using the fact that the comoving angular diameter distance to the last scattering surface is strictly constrained almost model independently, we show that, for any model agreeing w…
