The Intergalactic Magnetic Field (IGMF), though significantly weaker than the Galactic Magnetic Field (GMF), is believed to permeate the vast cosmic voids. Recent experimental developments have provided both upper and lower bounds on the IGMF, motivating us to revisit the scenario in which Magnetic Monopoles (MMs) are accelerated by these large-scale fields. In this work, we analyze MM acceleration in the IGMF and GMF, finding that the inclusion of IGMF effects calls for an update of the long-standing Parker bound.
Magnetic Monopoles—predicted in several extensions of the Standard Model—offer a compelling probe of cosmic magnetic fields. By modeling their acceleration mechanisms, we establish a unified framework connecting monopole mass, flux, and velocity at Earth. This approach allows us to reinterpret current experimental constraints, often reported in terms of Lorentz factor, in a more physically comprehensive manner.
Particular emphasis will be placed on the sensitivity of present and future Imaging Atmospheric Cherenkov Telescopes (IACTs), such as the Cherenkov Telescope Array (CTA), in the search for MMs.
