Event Details

The non-detection to date of any supersymmetric particles at the LHC, coupled with the large measured value of the Higgs boson, has increased interest in dark matter candidates other than the LSP. One such particle is the keV sterile neutrino, which forms part of a theory that may also explain the masses of known neutrinos and baryogenesis. Further motivation for this hypothesis has come from multiple claimed detections of an X-ray line at 3.5keV in the spectra of clusters of galaxies, M31 and the Galactic centre, which could be produced the decay of sterile neutrino dark matter. In this talk, Dr. Lovell will discuss the progress of work on the 3.5keV line by use of dark matter halo simulations, and also discuss the consequences of sterile neutrino dark matter for galaxy formation.
