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…
Observational constraints on the deceleration parameter in a tilted universe
Kerkyra Asvesta, Lavrentios Kazantzidis, Leandros Perivolaropoulos +1
We study a parametrization of the deceleration parameter in a tilted universe, namely a cosmological model equipped with two families of observers. The first family follows the smo…
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…
Hints for possible low redshift oscillation around the best fit CDM model in the expansion history of the Universe
L. Kazantzidis, H. Koo, S. Nesseris +2
We search for possible deviations from the expectations of the concordance CDM model in the expansion history of the Universe by analysing the Pantheon Type Ia Supernovae (SnIa)…
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…
Hints of a Local Matter Underdensity or Modified Gravity in the Low Pantheon data
L. Kazantzidis, L. Perivolaropoulos
A redshift tomography of the Pantheon type Ia supernovae (SnIa) data focusing on the best fit value of the absolute magnitude and/or Hubble constant in the context of …
