Reconstructing the generalized Barrow holographic dark energy with physics-informed neural networks
Spyros Basilakos, Andronikos Paliathanasis, Emmanuel N. Saridakis +1
Barrow holographic dark energy connects cosmic acceleration with possible quantum-gravitational deformations of horizon entropy, encoded in the Barrow exponent . If such effects…
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 persistent and tensions motivate the search for new dark-energy mechanisms capable of modifying the late-time expansion history while preserving the successful earl…
Building an inertia dynamometer with vocational students: a low-budget apparatus for teaching rotational dynamics
Stylianos A. Tsilioukas
We report the design, construction, and classroom use of a low-cost inertia dynamometer, built as a year-long project-based learning (PBL) activity with adult students at a Greek E…
Topological dark energy from spacetime foam: A challenge for CDM
Fotios K. Anagnostopoulos, Stylianos A. Tsilioukas, Emmanuel N. Saridakis
Using only the standard considerations of spacetime foam and the Euclidean Quantum Gravity techniques known long ago, we result to a model of Topological Dark Energy (TDE) that com…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
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…
Topological dark energy from black-hole formations and mergers through the gravity-thermodynamics approach
Stylianos A. Tsilioukas, Nicholas Petropoulos, Emmanuel N. Saridakis
We apply the gravity-thermodynamics approach in the case of Einstein-Gauss-Bonnet theory, and its corresponding Wald-Gauss-Bonnet entropy, which due to the Chern-Gauss-Bonnet theor…
Dark energy from topology change induced by microscopic Gauss-Bonnet wormholes
Stylianos A. Tsilioukas, Emmanuel N. Saridakis, Charalampos Tzerefos
It is known that the appearance of microscopic objects with distinct topologies and different Euler characteristics, such as instatons and wormholes, at the spacetime-foam level in…
