A Running Spectral Index in Supersymmetric Dark-Matter Models with Quasi-Stable Charged Particles
Stefano Profumo, Kris Sigurdson, Piero Ullio +1
We show that charged-particles decaying in the early Universe can induce a scale-dependent or `running' spectral index in the small-scale linear and nonlinear matter power spectrum…
Statistical Imprints of SZ Effects in the Cosmic Microwave Background
Asantha Cooray, Daniel Baumann, Kris Sigurdson
We review several aspects of the Sunyaev-Zel'dovich (SZ) effect associated with the large scale baryon distribution and its characteristic signatures in the statistics of cosmic mi…
Dark-Matter Electric and Magnetic Dipole Moments
Kris Sigurdson, Michael Doran, Andriy Kurylov +2
We consider the consequences of a neutral dark-matter particle with a nonzero electric and/or magnetic dipole moment. Theoretical constraints, as well as constraints from direct se…
