Can the WMAP Haze really be a signature of annihilating neutralino dark matter?
Daniel T. Cumberbatch, Joe Zuntz, Hans Kristian Kamfjord Eriksen +1
Observations by the Wilkinson Microwave Anisotropy Probe (WMAP) satellite have identified an excess of microwave emission from the centre of the Milky Way. It has been suggested th…
Heavy Dark Matter Through the Higgs Portal
John March-Russell, Stephen M. West, Daniel Cumberbatch +1
Motivated by Higgs Portal and Hidden Valley models, heavy particle dark matter that communicates with the supersymmetric Standard Model via pure Higgs sector interactions is consid…
Solving the cosmic lithium problems with primordial late-decaying particles
Daniel Cumberbatch, Kazuhide Ichikawa, Masahiro Kawasaki +3
We investigate the modifications to predictions for the abundances of light elements from standard Big-Bang nucleosynthesis when exotic late-decaying particles with lifetimes excee…
Accounting for the Unresolved X-ray Background with Sterile Neutrino Dark Matter
Daniel Cumberbatch, Joseph Silk
We consider a scenario where keV sterile neutrinos constitute all of the currently inferred dark matter abundance, whose radiative decays could potentially account for the flux con…
Sterile neutrinos as subdominant warm dark matter
A. Palazzo, D. Cumberbatch, A. Slosar +1
In light of recent findings which seem to disfavor a scenario with (warm) dark matter entirely constituted of sterile neutrinos produced via the Dodelson-Widrow (DW) mechanism, we…
Difficulties for Compact Composite Object Dark Matter
Daniel T. Cumberbatch, Glenn D. Starkman, Joseph Silk
It has been suggested ``that DM particles are strongly interacting composite macroscopically large objects ... made of well known light quarks (or ... antiquarks)." In doing so it…
