A reanalysis of the latest SH0ES data for : Effects of new degrees of freedom on the Hubble tension
Leandros Perivolaropoulos, Foteini Skara
We reanalyze the recently released SH0ES data for the determination of . We focus on testing the homogeneity of the Cepheid+SnIa sample and the robustness of the results in th…
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…
Weak gravity on a CDM background
Radouane Gannouji, Leandros Perivolaropoulos, David Polarski +1
We consider Horndeski modified gravity models obeying stability, velocity of gravitational waves equals and quasistatic approximation (QSA) on subhorizon scales. We assum…
Scalar tachyonic instabilities in gravitational backgrounds: Existence and growth rate
L. Perivolaropoulos, F. Skara
It is well known that the Klein Gordon (KG) equation has tachyonic unstable modes on large scales () for in a flat Minkowski…
Tension of the statistic and RSD data with Planck/CDM and implications for weakening gravity
F. Skara, L. Perivolaropoulos
The statistic is a powerful probe for detecting deviations from GR by combining weak lensing (WL), real-space clustering and redshift space distortion (RSD) measurements thus…
Primordial Power Spectra of Cosmological Fluctuations with Generalized Uncertainty Principle and Maximum Length Quantum Mechanics
F. Skara, L. Perivolaropoulos
The existence of the cosmological particle horizon as the maximum measurable length in the universe leads to a generalization of the quantum uncertainty principle (GUP) t…
