Cosmic ray lepton puzzle in the light of cosmological N-body simulations
Pierre Brun, Timur Delahaye, Juerg Diemand +2
The PAMELA and ATIC collaborations have recently reported an excess in the cosmic ray positron and electron fluxes. These lepton anomalies might be related to cold dark matter (CDM…
Infall caustics in dark matter halos?
J. Diemand, M. Kuhlen
We show that most particle and subhalo orbits in simulated cosmological cold dark matter halos are surprisingly regular and periodic: The phase space structure of the outer halo re…
The shapes, orientation, and alignment of Galactic dark matter subhalos
M. Kuhlen, J. Diemand, P. Madau
We present a study of the shapes, orientations, and alignments of Galactic dark matter subhalos in the ``Via Lactea'' simulation of a Milky Way-size LCDM host halo. Whereas isolate…
Early supersymmetric cold dark matter substructure
Juerg Diemand, Michael Kuhlen, Piero Madau
Earth-mass ``microhalos'' may be the first objects to virialize in the early universe. Their ability to survive the hierarchical clustering process as substructure in the larger ha…
