A Multi-Probe ISW Study of Dark Energy Models with Negative Energy Density: Galaxy Correlations, Lensing Bispectrum, and Planck ISW-Lensing Likelihood
Payam Ghafari, Mahdi Najafi, Mina Ghodsi Yengejeh +3
We investigate the late-time imprints of three dark energy (DE) models, namely, the Chevallier-Polarski-Linder (CPL) parametrization, CDM, and an Omnipotent DE model, on…
Dynamical Dark Energy Meets Varying Electron Mass: Implications for Phantom Crossing and the Hubble Constant
Adam Smith, Emre Özülker, Eleonora Di Valentino +1
We investigate the interplay between varying electron mass () and dynamical dark energy by analysing the Chevallier-Polarski-Linder (CPL) parametrization and its non-crossing…
Dark Energy Crosses the Line: Quantifying and Testing the Evidence for Phantom Crossing
Emre Özülker, Eleonora Di Valentino, William Giarè
Combinations of the most recent CMB, BAO, and SNeIa datasets, when analyzed using the CPL parametrization, , exclude CDM at in favor of a…
Updated Constraints on Omnipotent Dark Energy: A Comprehensive Analysis with CMB and BAO Data
Enrico Specogna, Shahnawaz A. Adil, Emre Ozulker +4
In this work, we present updated observational constraints on the parameter space of the DMS20 dark energy model, a member of the omnipotent dark energy (ODE) class. Our analysis c…
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.…
Exploring the Growth-Index () Tension with CDM
Luis A. Escamilla, Özgür Akarsu, Eleonora Di Valentino +2
Recent observational analyses have revealed a significant tension in the growth index , which characterizes the growth rate of cosmic structures. Specifically, when treating …
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…
Is the dark energy equation of state parameter singular?
Emre Ozulker
A dark energy with a negative energy density in the past can simultaneously address various cosmological tensions, and if it is to be positive today to drive the observed accelerat…
