Realistic Cyclic Magnetic Universe

Understand

This work presents a complete cyclic cosmological scenario based on nonlinear magnetic field.

• It is constructed a model composed by five fluids namely baryonic matter, dark matter, radiation, neutrinos and a cosmological magnetic field.
• The first four fluids are treated in the standard way and the fifth fluid, the magnetic field, is described by a nonlinear electrodynamics.
• The free parameters are fitted by observational data (SNIa, CMB, extragalactic magnetic fields, etc) and by simple theoretical considerations.
