Review: Recent Advances in Beyond the Standard Model Cosmology

Cosmology, 기본 / 글쓴이

arXiv:2401.04735 : Recent advances of Beyond the Standard model cosmology Introduction: The standard cosmological model incorporates concepts like inflation, baryosynthesis, and dark matter/energy, which are believed to extend Beyond the Standard Model (BSM) of fundamental physics. The paper explores various BSM cosmological features, which include signals that challenge the standard ΛCDM cosmology. These signals are …

Density Parameter (Ω)

Cosmology / 글쓴이

Density Parameter ( Ω )  The density parameter is a dimensionless quantity used in cosmology to describe the ratio of the actual density of matter or energy in the universe to the critical density. The critical density is the density required for the universe to be flat, meaning that it has just enough mass and …
