Small scale WIMP physics
Anne M. Green, Stefan Hofmann, Dominik J. Schwarz
The dark matter distribution on small scales may depend on the the properties of the first generation of dark matter halos to form, which is in turn determined by the microphysics…
Difficulty of detecting minihalos via -rays from dark matter annihilation
Lidia Pieri, Enzo Branchini, Stefan Hofmann
Analytical calculations and recent numerical experiments have shown that a sizable of the mass in our Galaxy is in a form of clumpy, virialized substructures that, according to \ci…
The first WIMPy halos
Anne M. Green, Stefan Hofmann, Dominik J. Schwarz
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…
The Spectrum of Fluctuations in Singularity-free Inflationary Quantum Cosmology
S. Hofmann, O. Winkler
We calculate the power spectrum of vacuum fluctuations of a generic scalar field in a quantum cosmological setting that is manifestly singularity-free. The power spectrum is given…
The power spectrum of SUSY-CDM on sub-galactic scales
Anne M. Green, Stefan Hofmann, Dominik J. Schwarz
The formation of large scale structure is independent of the nature of the cold dark matter (CDM), however the fate of very small scale inhomogeneities depends on the micro-physics…
Formation of small-scale structure in SUSY CDM
S. Hofmann, D. J. Schwarz, H. Stocker
The lightest supersymmetric particle, most likely the lightest neutralino, is one of the most prominent particle candidates for cold dark matter (CDM). We show that the primordial…
Damping of inhomogeneities in neutralino dark matter
Dominik J. Schwarz, Stefan Hofmann, Horst Stoecker
The lightest supersymmetric particle, most likely the neutralino, might account for a large fraction of dark matter in the Universe. We show that the primordial spectrum of density…
Damping scales of neutralino cold dark matter
Stefan Hofmann, Dominik J. Schwarz, Horst Stoecker
The lightest supersymmetric particle, most likely the neutralino, might account for a large fraction of dark matter in the Universe. We show that the primordial spectrum of density…
Small-scale structure of cold dark matter
Dominik J. Schwarz, Stefan Hofmann
We investigate the clumping of cold dark matter (CDM) at small scales. If the CDM particle is the neutralino, we find that collisional damping during its kinetic decoupling from th…
