ETHOS—an effective theory of structure formation: From dark particle physics to the matter distribution of the Universe
We formulate an effective theory of structure formation (ETHOS) that enables cosmological structure formation to be computed in almost any microphysical model of dark matter physics. This framework…
Fermi LAT Search for Internal Bremsstrahlung Signatures from Dark Matter Annihilation
A commonly encountered obstacle in indirect searches for galactic dark matter is how to disentangle possible signals from astrophysical backgrounds. Given that such signals are most likely…

New gamma-ray contributions to supersymmetric dark matter annihilation
We compute the electromagnetic radiative corrections to all leading annihilation processes which may occur in the Galactic dark matter halo, for dark matter in the framework of supersymmetric…
Pre-launch estimates for GLAST sensitivity to dark matter annihilation signals
We investigate the sensitivity of the Gamma-ray Large Area Space Telescope (GLAST) for indirectly detecting weakly interacting massive particles (WIMPs) through the γ-ray signal that their pair…

The nature of dark matter remains one of the key science questions. Weakly Interacting Massive Particles (WIMPs) are among the best motivated particle physics candidates, allowing to explain the…
Improved constraints on the primordial power spectrum at small scales from ultracompact minihalos
For a Gaussian spectrum of primordial density fluctuations, ultracompact minihalos (UCMHs) of dark matter are expected to be produced in much greater abundance than, e.g., primordial black holes.…
ETHOS - an effective theory of structure formation: dark matter physics as a possible explanation of the small-scale CDM problems
We present the first simulations within an effective theory of structure formation (ETHOS), which includes the effect of interactions between dark matter and dark radiation on the linear initial…
Novel Direct Detection Constraints on Light Dark Matter.
This work derives novel constraints from the inevitable existence of a subdominant, but highly energetic, component of DM generated through collisions with cosmic rays that limits the DM-nucleon scattering cross section to be below 10-31-31cm2 for both spin-independent and spin-dependent scattering of light DM.

It is pointed out that in such models the dark matter annihilation rate is generically enhanced by the Sommerfeld effect, and the resulting constraints from the cosmic microwave background and other indirect detection probes are derived.
