Examining extinction distributions for type Ia supernovae in simulated 3D galaxies
João Duarte, Santiago González-Gaitán, Ana M. Mourão +2
Dust extinction and reddening greatly contribute to type Ia supernovae (SNe Ia) observed color and magnitude variations. The models used to describe the extinction probability dens…

Missing Components in ÎCDM from DESI Y1 BAO Measurements: Insights from Redshift Remapping
E. Fernández-GarcÃa, R. Wojtak, F. Prada +39
We explore transformations of the Friedman-Lemaître-Robertson-Walker (FLRW) metric and cosmological parameters that align with observational data, aiming to gain insights into pot…

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.…
