Description
On their journey from their sources to Earth, electrically-charged cosmic rays are deflected by magnetic fields.
While small-scale magnetized structures have no impact on the propagation of ultra-high energy cosmic rays, they can have an impact on our reconstruction of the large-scale magnetic field obtained from synchrotron and Faraday rotation data. In this context, the Local Bubble, a cavity of hot gas surrounded by a thick magnetized dusty shell, is perhaps one of the most important foregrounds to be taken into account as it surrounds us.
In this talk, I will discuss the effect of the Local Bubble on state-of-the-art reconstructions of the coherent Galactic magnetic field and its implications for the study of UHECR arrival direction data.
