超高能宇宙射线的磁视界

Magnetic horizons of ultra-high energy cosmic rays

Rafael Alves Batista, Guenter Sigl

摘要:

超高能宇宙射线在河外磁场中的传播可以是扩散的,这取决于磁场的强度和性质。在某些情况下,粒子的传播时间可以与宇宙的年龄相媲美,导致在地球上测量的通量受到抑制。在这项工作中,我们使用宇宙学模拟的磁场分布,以评估在能量约10 $^{18}$ eV的磁视界的存在。

英文摘要:

The propagation of ultra-high energy cosmic rays in extragalactic magnetic fields can be diffusive, depending on the strength and properties of the fields. In some cases the propagation time of the particles can be comparable to the age of the universe, causing a suppression in the flux measured on Earth. In this work we use magnetic field distributions from cosmological simulations to assess the existence of a magnetic horizon at energies around 10$^{18}$ eV.
