A lower bound on the mass of cold thermal dark matter from Planck
We show that the new measurement of the effective number of neutrinos (Neff) by the Planck satellite can be used to set a robust lower bound on the mass of cold thermal dark matter of (MeV). Our
Large scale structure in Bekenstein's theory of relativistic modified Newtonian dynamics.
TLDR
It is shown that it may be possible to reproduce observations of the cosmic microwave background and galaxy distributions with Bekenstein's theory of MOND, and the evolution of the scalar field is akin to that of tracker quintessence fields.
Dark Sectors 2016 Workshop: Community Report
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the weak-scale, the
The 511 keV emission from positron annihilation in the Galaxy
The first $\ensuremath{\gamma}$-ray line originating from outside the Solar System that was ever detected is the 511 keV emission from positron annihilation in the Galaxy. Despite 30 years of intense
MeV dark matter: has it been detected?
TLDR
It is found that the possibility that the recent detection of 511 keV gamma rays from the galactic bulge, as observed by INTEGRAL, is a consequence of low mass particle dark matter annihilations is consistent with the observed dark matter relic density and other constraints from astrophysics and particle physics.
First look at the physics case of TLEP
A bstractThe discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV and with measured properties compatible with those of a Standard-Model Higgs boson, coupled with the

Constraints on dark matter and the shape of the Milky Way dark halo from the 511-keV line
About one year ago, it was speculated that decaying or annihilating light dark matter (LDM) particles could explain the flux and extension of the 511-keV line emission in the Galactic Centre. Here,
Constraining dark matter-neutrino interactions using the CMB and large-scale structure
We present a new study on the elastic scattering cross section of dark matter (DM) and neutrinos using the latest cosmological data from Planck and large-scale structure experiments. We find that the
