The impact of Hawking radiation from primordial black holes on recombination and the Hubble tension
Adam Batten, Jeremy Mould
Primordial black holes (PBHs) evaporate through Hawking radiation, emitting high-energy photons and ionising their surrounding environment. As contributors to the density of dark m…
Is dark matter decaying ?
Jeremy Mould
An enduring signature of the decay of unstable dark matter constituents into other particles would manifest as a measurable discrepancy in the matter density parameter (Omega_m) be…
Accelerating massive galaxy formation with primordial black hole seed nuclei
Jeremy Mould
If massive primordial black holes (PBHs) exist and constitute a fraction of the dark matter, they can dramatically catalyze galaxy formation. By acting as pre-existing, high-densit…
Are carbon deflagration supernovae triggered by dark matter ?
Jeremy Mould
Collisions between stellar remnants and dark matter in the Galactic bulge are frequent, and the kinetic energy of a primordial black hole incident on a white dwarf, if it is all th…
If quasars form from primordial black holes
Jeremy Mould, Adam Batten
We explore the consequences of a novel but increasingly well-supported hypothesis that supermassive black holes may have formed from primordial black holes form ed prior to, and ra…
More power on large scales
Jeremy Mould
The high value of the cosmic microwave dipole may be telling us that dark matter is macroscopic rather than a fundamental particle. The possible presence of a significant dark matt…
