Temperature effects on white dwarfs in modified gravity
Sofía Vidal, Aneta Wojnar, Laur Järv
In this article we analyze the effects of a finite temperature equation of state on the equilibrium structure of white dwarfs in massive Brans-Dicke theory as well as the symmetron…
Einstein crystals in Snyder and Snyder-de Sitter noncommutative backgrounds
Anna PachoÅ, Aneta Wojnar
We investigate the behavior of Einstein crystals in noncommutative backgrounds described by the Snyder and Snyder-de Sitter models. Possible novel effects, which may arise in reali…
When waves meet rays: Seismic vibrations and cosmic showers to test gravity
Aneta Wojnar
We propose a novel laboratory test of gravity combining seismic-wave measurements with cosmic-ray muon detections. Quantum-gravity corrections to the anharmonic Debye model are der…
The effects of strong gravity on the dispersion relation of massive particles in the Kaluza-Klein theory
Anna Horváth, Aneta Wojnar, Gergely Gábor Barnaföldi
We derive a modified dispersion relation for massive particles within the frameworks of five-dimensional Kaluza-Klein theory and general relativity, taking into account strong grav…
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.…
Refining Bounds for Snyder and GUP Models through Seismic Wave Analysis
Aleksander Kozak, Anna PachoÅ, Aneta Wojnar
This study investigates possibility of placing bounds on the parameters, arising from the non-commutative Snyder space-time model and Generalized Uncertainty Principle (GUP) approa…
