Abstract
The Earth is bombarded with cosmic-rays (CRs) from all directions isotropically. These energetic particles are believed to be accelerated in various galactic and extra-galactic sources. The flux of these CRs are extended over \(\sim \)12 orders of energies starting from \(10^{9}eV\) [1]. But the sources of these energetic particles are still unknown. Being charged these particles are deflected in their path by galactic or extra-galactic magnetic fields, as a result they never point back to their sources.
