AMPM II. A Lunar-Mass Primordial Black Hole Microlensing Candidate in the Milky Way Halo
Renee Key, Edward N. Taylor, Ken C. Freeman +5
Primordial Black Holes (PBH) are hypothesised to form during inflation and have long been considered a candidate for compact dark matter. Gravitational microlensing is known as a p…

AMPM I. A Targeted Search for Asteroid Mass Primordial Black Hole Microlenses
Renee Key, Edward N. Taylor, Ken C. Freeman +5
Gravitational microlensing is a powerful technique for constraining the abundance of dark matter in asteroid mass to supermassive primordial black holes at masses of $-11 \lesssim…

Tidal adaptive softening and artificial fragmentation in cosmological simulations
Robert A. Mostoghiu Paun, Darren Croton, Chris Power +3
Traditional N-body methods introduce localised perturbations in the gravitational forces governing their evolution. These perturbations lead to an artificial fragmentation in the f…
