Magnetic Monopoles are accelerated by cosmic magnetic fields in relation to their mass and number, due to back-reaction. After recent experimental lower limits on the intergalactic magnetic fields (IGMFs), we have revisited a coherent acceleration scenario in which monopoles are accelerated in intergalactic and Galactic magnetic fields before reaching the Earth (Phys.Dark Univ. 46 (2024))....
Axion-like particles (ALPs) are weakly interacting particles that are predicted to exist by many beyond standard model theories. A large number of experiments have been constructed or are under construction to search for these ALPs both directly and indirectly (through astrophysical or cosmological observations). In this work we have studied how photon signals originating from the oscillation...
The “memory burden” effect describes how an object’s stored information resists its own decay. This effect is especially pronounced in “saturons”—systems with maximal entropy consistent with unitarity—of which black holes are prime examples. I will show how this memory burden can halt Hawking evaporation, stabilizing black holes against complete decay. Importantly, this mechanism is not...
Observation of an exploding black hole would provide the first direct evidence of primordial black holes, the first direct evidence of Hawking radiation, and definitive information on the particles present in nature. However, indirect constraints suggest that direct observation of an exploding Schwarzschild black hole is implausible. We introduce a dark-QED toy model consisting of a dark...
