Clustering of Primordial Black Holes. II. Evolution of Bound Systems
James R. Chisholm
Primordial Black Holes (PBHs) that form from the collapse of density perturbations are more clustered than the underlying density field. In a previous paper, we showed the constrai…
Primordial Black Hole Minimum Mass
James R. Chisholm
In this paper we revisit thermodynamic constraints on primordial black hole (PBH) formation in the early universe. Under the assumption that PBH mass is equal to the cosmological h…
Clustering of primordial black holes: Basic results
James R. Chisholm
We investigate the spatial clustering properties of primordial black holes (PBHs). With minimal assumptions, we show that PBHs created in the radiation era are highly clustered. Us…
Lorentz invariance violation in top-down scenarios of ultrahigh energy cosmic ray creation
James R. Chisholm, Edward W. Kolb
The violation of Lorentz invariance (LI) has been invoked in a number of ways to explain issues dealing with ultrahigh energy cosmic ray (UHECR) production and propagation. These t…
