Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Late time approaches to the Hubble tension deforming , worsen the growth tension
G. Alestas, L. Perivolaropoulos
Many late time approaches for the solution of the Hubble tension use late time smooth deformations of the Hubble expansion rate of the Planck18/CDM best fit to match the…
Hints for a gravitational constant transition in Tully-Fisher data
George Alestas, Ioannis Antoniou, Leandros Perivolaropoulos
We use an up to date compilation of Tully-Fisher data to search for transitions in the evolution of the Tully-Fisher relation. Using an up to date data compilation, we find hints a…
A phantom transition at as a resolution of the Hubble tension
George Alestas, Lavrentios Kazantzidis, Leandros Perivolaropoulos
A rapid phantom transition of the dark energy equation of state parameter at a transition redshift of the form with can lead to a higher…
Existence and Stability of Static Spherical Fluid Shells in a Schwarzschild-Rindler-anti-de Sitter Metric
G. Alestas, G. V. Kraniotis, L. Perivolaropoulos
We demonstrate the existence of static stable spherical fluid shells in the Schwarzschild-Rindler-anti-de Sitter (SRAdS) spacetime where $ds^2 = f(r)dt^{2} -\frac{dr^{2}}{f(r)}-r^{…
Tension, Phantom Dark Energy and Cosmological Parameter Degeneracies
G. Alestas, L. Kazantzidis, L. Perivolaropoulos
Phantom dark energy can produce amplified cosmic acceleration at late times, thus increasing the value of favored by CMB data and releasing the tension with local measurement…
