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…
Cosmological Interactions with Phantom Scalar Field: Revisiting Background Phase-Space Analysis with Compactified Variables
Genly Leon, Daya Shankar, Amlan Halder +1
Energy transfer in the dark sector of the universe gives rise to new phenomena of special interest in modern cosmology. When dark energy is modeled as a phantom scalar field, inter…
Revise the Dark Matter-Phantom Scalar Field Interaction
Andronikos Paliathanasis, Amlan Halder, Genly Leon
The cosmological history and evolution are examined for gravitational models with interaction in the dark sector of the universe. In particular, we consider the dark energy to be d…
Compartmentalization and Coexistence in the Dark Sector of the Universe
Andronikos Paliathanasis, Kevin Duffy, Amlan Halder +1
We revise the cosmological interaction between dark energy and dark matter. More precisely, we focus on models that support compartmentalization or co-existence in the dark sector…
Kantowski-Sachs and Bianchi III dynamics in -gravity
Alfredo D. Millano, K. Dialektopoulos, N. Dimakis +4
We explore the phase-space of homogeneous and anisotropic spacetimes within symmetric teleparallel -gravity. Specifically, we consider the Kantowski-Sachs and locally rotatio…
