Neutrino cosmology and Planck

New Journal of Physics, 2014
Relic neutrinos play an important role in the evolution of the Universe, modifying some of the cosmological observables. We summarize the main aspects of cosmological neutrinos and describe how the precision of present cosmological data can be used to ...

Measuring the Redshift-space Distortions by Cross-correlating the Density Fields Before and After Reconstruction

The Astrophysical Journal
In this work, we develop a theoretical model for the cross-power spectrum of the matter density field before and after standard baryonic acoustic oscillation reconstruction.

Observational constraints on entropic cosmology

Physics Letters B
In this work, we derive a generalized modified Friedmann equation based on an entropy-area relation that incorporates established modifications, such as volumetric, linear, and logarithmic terms, in addition to novel entropic modifications that might ...

Uncorrelated Estimations of H0 Redshift Evolution from DESI Baryon Acoustic Oscillation Observations

The Astrophysical Journal Letters
The Dark Energy Spectroscopic Instrument (DESI) collaboration recently released the first-year data of baryon acoustic oscillations (BAOs). Based on the five different tracers, the cosmological constraint shows a hint of deviation from the standard ΛCDM ...
