Low-Mass Magnetic Monopoles in the Galaxy: Simulations and Comparison with Ultra-High-Energy Cosmic-Ray Data
Ala'a AL-Zetoun, Igor Ostrovskiy, Peiwen Mi +1
Origin and composition of ultra-high energy cosmic rays are still uncertain, particularly the rare events exceeding the Greisen-Zatsepin-Kuzmin cutoff and whose apparent arrival di…

Constraints on magnetic monopoles from X-ray observations of neutron stars
Mainak Mukhopadhyay, Daniele Perri, Edward W. Kolb
Magnetic monopoles are captured efficiently by neutron stars, and if they catalyze nucleon decay, the decay products would thermalize and generate observable X-ray surface emission…
