A $w - M$ phantom transition at $z_{t} < 0.1$ 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 $w$ at a transition redshift $z_{t} < 0.1$ of the form $w (z) = - 1 + Δ w Θ (z_{t} - z)$ with $Δ w < 0$ 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^{…

$H_{0}$ 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 $H_{0}$ favored by CMB data and releasing the tension with local measurement…
