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…
Recasting Experimental Constraints on Relativistic Magnetic Monopoles
Daniele Perri, Michele Doro, Takeshi Kobayashi
Magnetic monopoles with masses up to GeV can be accelerated to relativistic velocities in Galactic and intergalactic magnetic fields. The cosmic flux of relativistic mono…
Gravothermalizing into primordial black holes, boson stars, and cannibal stars
Pranjal Ralegankar, Daniele Perri, Takeshi Kobayashi
Very little is known about the cosmological history from after the end of inflation until Big Bang Nucleosynthesis. Various well-motivated models predict that the universe could ha…
Monopole acceleration in intergalactic magnetic fields
Daniele Perri, Kyrilo Bondarenko, Michele Doro +1
We provide a comprehensive analysis of the acceleration of magnetic monopoles in intergalactic magnetic fields. We demonstrate that monopoles with intermediate to low masses can be…
