Viaggiu holographic dark energy in light of DESI DR2
Amlan K. Halder, Andronikos Paliathanasis, Stefano Viaggiu +2
We test the cosmological viability of the Viaggiu holographic dark energy (VHDE) model by using late-time observational data. In particular, we place constraints on the free parame…
Observational Constraints on Noncoincident -Gravity with Matter-Gravity Coupling
Andronikos Paliathanasis
We investigate -gravity with a matter-gravity coupling as a geometric dark energy candidate for the description of the late-time cosmic acceleration within a spa…
Dynamics of the Bianchi~V cosmological model inspired by quintessential -attractors
Genly Leon, Amare Abebe, Andronikos Paliathanasis
We investigate scalar-field cosmologies in the Bianchi V spacetime using a dynamical-systems framework. Motivated by representative -attractor potentials - the E-model and T-mod…
Hints Beyond CDM from Barrow and Tsallis Holographic Dark Energy with GO cutoff
G. G. Luciano, A. Paliathanasis, G. Leon +2
Barrow and Tsallis Holographic Dark Energy (HDE) are two recent extensions of the standard HDE framework, obtained by introducing generalized entropy corrections through the Barrow…
Observational constraints on the modified cosmology inspired by string T-duality
G. G. Luciano, A. Paliathanasis, A. Sheykhi
We explore the cosmological consequences of a modified cosmology inspired by string T-duality. We incorporate the zero-point length correction, , into the gravitational potent…
