We review several current aspects of dark matter theory and experiment. We overview the
present experimental status, which includes current bounds and recent claims and hints of a …

We present an overview of scenarios where the observed Dark Matter (DM) abundance
consists of Feebly Interacting Massive Particles (FIMPs), produced nonthermally by the so …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

Sterile neutrinos with masses in the keV range are well-motivated extensions to the
Standard Model that could explain the observed neutrino masses while also making up the …

We present two complementary NuSTAR x-ray searches for keV-scale dark matter decaying
to monoenergetic photons in the Milky Way halo. In the first, we utilize the known intensity …

Astrophysical Limits on Very Light Axion-like Particles from Chandra Grating Spectroscopy of
NGC 1275 - IOPscience This site uses cookies. By continuing to use this site you agree to our …

The X-Ray Imaging and Spectroscopy Mission (XRISM) is the successor to the 2016 Hitomi
mission that ended prematurely. Like Hitomi, the primary science goals are to examine …

We investigate the effects of producing dark matter by the Hawking evaporation of primordial
black holes (PBHs) in scenarios that may have a second well-motivated dark matter …

We review sterile neutrinos as possible Dark Matter candidates. After a short summary on
the role of neutrinos in cosmology and particle physics, we give a comprehensive overview …

We use a combined 1.2 Ms of NuSTAR observations of M31 to search for x-ray lines from
sterile neutrino dark matter decay. For the first time in a NuSTAR analysis, we consistently …
