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…
Dynamical Dark Energy Meets Varying Electron Mass: Implications for Phantom Crossing and the Hubble Constant
Adam Smith, Emre Ãzülker, 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…
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, o…
The Local Distance Network: a community consensus report on the measurement of the Hubble constant at 1% precision
H0DN Collaboration, Stefano Casertano, Gagandeep Anand +35
The direct, empirical determination of the local value of the Hubble constant (H0) has markedly advanced thanks to improved instrumentation, measurement techniques, and distance es…
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.…
Dark Energy Crosses the Line: Quantifying and Testing the Evidence for Phantom Crossing
Emre Ãzülker, 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…
