真实的循环磁宇宙

Realistic Cyclic Magnetic Universe

L. G. Medeiros

摘要:

本文提出了一个完整的基于非线性磁场的循环宇宙学方案。它由重子物质、暗物质、辐射、中微子和宇宙磁场五种流体组成。前四种流体以标准方式处理,第五种流体,磁场,由非线性电动力学描述。自由参数由观测数据(SNIa,CMB,河外磁场等)和简单的理论考虑来拟合。由此产生了一个循环宇宙学模型,它保留了标准大爆炸模型的主要成就,并解决了初始奇点、当前加速度和大撕裂等问题。

英文摘要:

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. As result arises a cyclic cosmological model which preserves the main successes of standard big bang model and solve some other problems like the initial singularity, the present acceleration and the Big Rip.
