Solutions for neutron stars in General Relativity from a complexity structure scalar boundary condition
Robert S. Bogadi, Megandhren Govender, Genly Leon +1
A new condition involving the complexity factor, a structure scalar arising from the orthogonal splitting of the Riemann tensor, is generated at the boundary of a spherically symme…
Observational constraints on Barrow holographic dark energy coupled with a non-cold dark matter component from DESI DR2
Abdulla Al Mamon, Genly Leon, Subhajit Saha +1
We investigate the cosmological viability of Barrow holographic dark energy in a spatially flat Friedmann--Lema\^ıtre--Robertson--Walker universe in which the dark matter component…
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…
Bianchi I spacetimes within 4D Einstein-Gauss-Bonnet scalar field theory
Alex Giacomini, Chevara Hansraj, Genly Leon +1
We investigate the evolution of anisotropies in Bianchi I spacetimes within the framework of the 4D Einstein-Gauss-Bonnet scalar field theory. The field equations are formulated us…
Constraints on Chiral-Quintom dark energy after DESI DR2 and impact on unifying dark energy with inflation
Andronikos Paliathanasis, Tommaso Mengoni, Genly Leon +1
The recent data release DR2 from the Dark Energy Spectroscopic Instrument (DESI) has reinforced compelling evidence supporting the dynamical nature of dark energy. In this respect,…
Averaging Dynamics of Scalar Field-Matter Interacting Models in Anisotropic Universes: The Locally Rotationally Symmetric Bianchi I Spacetime
Alfredo D. Millano, Genly Leon, Andronikos Paliathanasis
We consider an anisotropic cosmological model based on the locally rotational Bianchi I spacetime, incorporating a scalar field and a non-zero cosmological interaction term. The fr…
