My main research so far has focussed on dark matter in the context of
supersymmetry and models with large extra dimensions. Further interests include cosmic rays, primordial black holes and general relativity. I have written a short popular introduction to some of these topics; for more details,
please have a look at a my articles and the references
therein (e.g. a recent review on dark matter searches with gamma rays). If you are interested in some general introductory information
to cosmology, see for example the Cambridge Cosmology site
or Martin Whites collection of tutorials.
I am also one of the authors of DarkSUSY, a publicly available numerical package to compute dark matter properties in supersymmetric and other frameworks. Recent additions include, e.g., internal bremsstrahlung and the small-scale cutoff in the power spectrum of density perturbations for WIMP dark matter.

"From Dark Matter Properties to the Fundamental Theory"
(DFG grant BR 3954/1-1)
Cosmology, and dark matter physics in particular, is an extremely timely subject that consequently has developed into one of the key science questions in recent years. Remarkably, due to its interdisciplinary nature, the subject will receive significant input from shortly upcoming experiments as different as accelerators (the LHC, in particular), various new ground- and space-based telescopes as well as dark matter detectors on earth. On the theoretical side, this is complemented with many interesting new ideas, indicating that these are very exciting times for cosmology, where already the near future might witness a solution to the dark matter puzzle.
Our group aims at making use of the complementarity between these approches to devise promising strategies for determining as precisely as possible the nature and the detailed properties of the dark matter, thereby gaining insight into the underlying fundamental theory.
More specifically, the group's research interests include:
- Implications of radiative corrections ("internal bremsstrahlung") and non-perturbative effects ("Sommerfeld enhancements")
on dark matter annihilation
- Multi-messenger and multi-wavelength strategies for the indirect detection of dark matter
- Dark matter and collider physics; complementarity with other approaches
- The small-scale distribution of (dark) matter
- Strategies for the detection of non-WIMP dark matter candidates
Currently, the group consists of myself, Masaki Asano
Francesca Calore (PhD student),
Martin Vollmann (PhD student) and Benedict Broy (Master student); former members are
Mitsuru Kakizaki (now at Toyama university), Laura van den Aarssen (PhD 2012) and
Yasar Goedecke (Diploma 10/2011).
It is embedded in the AstroParticle theory group at
Hamburg university and also a member of the collaborative research project SFB 676
on "Particles, strings and the early universe: the structure of matter and spacetime." Dark matter is a research
interest shared with the DESY theory group and the
experimental AstroParticle group at Hamburg University, both located on the same campus.
