Gamma-rays from ultracompact minihalos: potential constraints on the primordial curvature perturbation
Amandeep S. Josan, Anne M. Green
Ultracompact minihalos (UCMHs) are dense dark matter structures which can form from large density perturbations shortly after matter-radiation equality. If dark matter is in the fo…

Generalised constraints on the curvature perturbation from primordial black holes
Amandeep S. Josan, Anne M. Green, Karim A. Malik
Primordial black holes (PBHs) can form in the early Universe via the collapse of large density perturbations. There are tight constraints on the abundance of PBHs formed due to the…
