Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray astronomy has a…
Constraints on the density perturbation spectrum from primordial black holes
We reexamine the constraints on the density perturbation spectrum, including its spectral index $n,$ from the production of primordial black holes. The standard cosmology, where the Universe is…
The power spectrum of SUSY-CDM on subgalactic scales

ABSTRACT The formation of large scale structure is independent of the nature of the cold darkmatter (CDM), however the fate of very small scale inhomogeneities depends on themicro-physics of the CDM…

Dark matter direct and indirect detection signals depend crucially on the dark matter distribution. While the formation of large scale structure is independent of the nature of the cold dark matter…
Astrophysical uncertainties on direct detection experiments

Direct detection experiments are poised to detect dark matter in the form of weakly interacting massive particles (WIMPs). The signals expected in these experiments depend on the ultra-local WIMP…
Direct detection of WIMPs.

If the Milky Way’s DM halo is composed of WIMPs, then the WIMP flux
on the Earth is of the order of 105(100 GeV/mχ)cm−2 s−1. This flux is suf-
ficiently large that, even though the WIMPs are weakly…
Astrophysical uncertainties on the local dark matter distribution and direct detection experiments

The differential event rate in weakly interacting massive particle (WIMP) direct detection experiments depends on the local dark matter density and velocity distribution. Accurate modelling of the…
Generalised constraints on the curvature perturbation from primordial black holes

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 their gravitational…
Gamma-rays from ultracompact minihalos: potential constraints on the primordial curvature perturbation
- A. S. Josan, A. Green
- Physics
- 25 June 2010
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 form of weakly…
