Descrição
In the study of cosmic rays in particle physics, one of the most interesting class of this object are ultra-high energy cosmic rays, originated from outer space with energies that surpasses 1 EeV (10^18 V) and composed by protons and heavier nuclei. However, even with their high energy, the identification of their detection is hindered by factors such as cosmic magnetic fields, which deflect the charged particles. But even if those ultra-high energy cosmic rays suffer deflection that deviates then from a straight path from their acceleration site, we can still extract hints of their origin with their distribution of arrival directions. One such example is the measurement by the Pierre Auger Observatory of a dipolar modulation in large scales anisotropies in the background, without the influence of our galaxy center. The aim of this work is to develop even further the understanding about the impact of astrophysical hypotheses in modeling the amplitude of the dipole measures by Pierre Auger Observatory. In this small presentation, I will show my preliminary results obtained in the simulations and propositions about the modeling. The simulations use the propagation code from CRPropa3, and with them, we aim to acquire new information of the ultra-high energy cosmic rays and of the background sources and it's constraints, while also finding more efficient ways to analyze the acceleration sources of ultra-high cosmic rays, while also speculating about possible results to be found with the CTA.
