Descripción
Modern Cosmology has become a precise discipline thanks to immense improvements in Cosmic Microwave Background (CMB) and Large Scale Structure (LSS) observations, in addition to an ameliorated theoretical description of cosmological models. However, this precision uncovered tensions between datasets that challenge the standard model of Cosmology, ΛCDM. In this talk, I present a brief overview of past and existing tensions, focusing mainly on the Hubble Tension and the rising potential tension between CMB and Baryon Acoustic Oscillations measurements from the Dark Energy Spectroscopic Instrument (DESI). In addition to showing the most up-to-date status of these tensions, I describe a few of the models presented to address these tensions.
