The effective interactions of dark matter with photons are fairly restricted. Yet both direct detection as well as monochromatic gamma ray signatures depend sensitively on the presence of such interactions. For a Dirac fermion,…
Light new particles with masses below 10 keV, often considered as a plausible extension of the Standard Model, will be emitted from the solar interior, and can be detected on the Earth with a variety of experimental tools. Here we analyze…

We discover that the mass of dark matter particles mDM is imprinted in phase-correlations of the cosmic density field more significantly than in the 2-point correlation. In particular, phase-correlations trace mDM out to scales about five…
