Early- and late-time constraints on Wald-Gauss-Bonnet topological dark energy and implications for the and tensions
Stylianos A. Tsilioukas, Fotios K. Anagnostopoulos, Spyros Basilakos +2
The paper investigates Wald‑Gauss‑Bonnet topological dark energy as a late‑time modification to the expansion history, performing early‑ and late‑Universe data analyses that show i…
Charting the expansion of the Universe from z0 to z14 with HII galaxies
R. Chávez, R. Terlevich, A. L. González-Morán +14
The authors construct an updated Hubble diagram using 243 giant H II regions and H II galaxies from redshift 0 to ~14, applying the L(Hβ)–σ relation to derive cosmological paramete…
Observational implications of Wald-Gauss-Bonnet topological dark energy
Maria Petronikolou, Fotios K. Anagnostopoulos, Stylianos A. Tsilioukas +2
We investigate the observational implications of Wald--Gauss--Bonnet (WGB) topological dark energy, a modified cosmological framework derived from the gravity-thermodynamics conjec…
Primordial black hole formation from transient cosmology
Gerasimos Kouniatalis, Theodoros Papanikolaou, Spyros Basilakos +1
We study primordial black hole (PBH) formation in a minimally coupled teleparallel cosmology that generates a transient departure from standard radiation domination. The mod…
Bohmian Quantum Cosmology from the Wheeler-DeWitt Equation
Spyros Basilakos, Gerasimos Kouniatalis, Emmanuel N. Saridakis +1
We construct a Bohmian quantum cosmological model for a spatially flat Friedmann Robertson Walker universe filled with a single scalar field whose potential provides a unified desc…
Highly suppressed tensor-to-scalar ratio from a modified Lennard-Jones inflationary potential
Panagiotis G. Stavros, Spyros Basilakos, Emmanuel N. Saridakis
The increasingly stringent observational bounds on primordial gravitational waves strongly constrain inflationary model building, favoring scenarios that predict highly suppressed…
