Strategy for searching for a dark matter sterile neutrino.
We propose a strategy for how to look for dark matter particles possessing a radiative decay channel and derive constraints on their parameters from observations of x rays from our own Galaxy and its dwarf satellites. When applied to sterile neutrinos in the keV mass range this approach gives a significant improvement to restrictions on neutrino parameters compared with previous works.
متن کاملEquilibrium configurations of 11 eV sterile neutrinos in MONDian galaxy clusters
Modified Newtonian Dynamics (MOND) can fit a broad range of galaxy kinematic data, but struggles with clusters of galaxies. MONDian clusters need dark matter, and here we test the 11 eV/c sterile neutrino used to fit the first three acoustic peaks of the cosmic microwave background by investigating their equilibrium distributions in 30 groups and clusters over a wide range of temperatures. We d...
متن کاملNew Limits on Sterile Neutrinos from Suzaku Observations of the Ursa Minor Dwarf Spheroidal Galaxy
We present results of our search for X-ray line emission associated with the radiative decay of the sterile neutrino, a well-motivated dark matter candidate, in Suzaku Observatory spectra of the Ursa Minor dwarf spheroidal galaxy. These data represent the first deep observation of one of these extreme mass-to-light systems and the first dedicated dark matter search using an X-ray telescope. No ...
متن کاملConstraints on the parameters of radiatively decaying dark matter from the dark matter halos of the Milky Way and Ursa Minor
Aims. We improve the earlier restrictions on parameters of the dark matter (DM) in the form of a sterile neutrino. Methods. The results were obtained from non-observing the DM decay line in the X-ray spectrum of the Milky Way (using the recent XMM-Newton PN blank sky data). We also present a similar constraint coming from the recent XMM-Newton observation of Ursa Minor – dark, X-ray quiet dwarf...
متن کاملCan sterile neutrinos be the dark matter?
We use the Ly-alpha forest power spectrum measured by the Sloan Digital Sky Survey and high-resolution spectroscopy observations in combination with cosmic microwave background and galaxy clustering constraints to place limits on a sterile neutrino as a dark matter candidate in the warm dark matter scenario. Such a neutrino would be created in the early Universe through mixing with an active ne...
