Cosmology with SKA
Orfeu Bertolami, Cl\'audio Gomes
TL;DR
This paper reviews how the Square Kilometer Array (SKA) will advance cosmology by measuring dark energy, dark matter, cosmic magnetism, and testing fundamental physics through various observational techniques.
Contribution
It highlights the potential of SKA to provide new insights into dark energy, dark matter, and cosmic magnetism, and discusses specific measurement strategies.
Findings
SKA can measure dark energy's equation of state via BAO.
SKA will probe dark matter power spectrum and modifications to gravity.
SKA will explore cosmic magnetism and its impact on universe dynamics.
Abstract
We review some of the major contributions that the Square Kilometer Array (SKA) will provide for Cosmology. We discuss the SKA measurements of the equation of state parameter for dark energy from Baryonic Acoustic Oscillations (BAO), of the dark matter power spectrum and modifications of the Poisson equation or the slip relation from weak lensing. We also comment on measurements of the cosmic magnetism and its role on the dynamics of the Universe.
