Constraining Models of Neutrino Mass and Neutrino Interactions with the Planck Satellite
Alexander Friedland, Kathryn M. Zurek, Sergei Bashinsky
In several classes of particle physics models -- ranging from the classical Majoron models, to the more recent scenarios of late neutrino masses or Mass-Varying Neutrinos -- one or…
MeV Dark Matter and Small Scale Structure
Dan Hooper, Manoj Kaplinghat, Louis E. Strigari +1
WIMPs with electroweak scale masses (neutralinos, etc.) remain in kinetic equilibrium with other particle species until temperatures approximately in the range of 10 MeV to 1 GeV,…
White Noise from Dark Matter: 21 cm Observations of Early Baryon Collapse
Kathryn M. Zurek, Craig J. Hogan
In concordance cosmology, dark matter density perturbations generated by inflation lead to nonlinear, virialized minihalos, into which baryons collapse at redshift . We…
Astrophysical Effects of Scalar Dark Matter Miniclusters
Kathryn M. Zurek, Craig J. Hogan, Thomas R. Quinn
We model the formation, evolution and astrophysical effects of dark compact Scalar Miniclusters (``ScaMs''). These objects arise when a scalar field, with an axion-like or Higgs-li…
