I will discuss how the identity of the dark matter is reflected in properties of small galaxies such as the satellites of the Milky Way. I will present a test, base on gravitational lensing, that can unambiguously distinguish between cold dark matter and other possibilities such as sterile neutrino dark matter. This test could, in principle, rule out one or the other.

I overview the dark matter model offering a very natural explanation of 3 (naively unrelated) problems in cosmology: the observed relation $\Omega_{\rm DM}\sim\Omega_{\rm visible}$, the observed asymmetry between matter and antimatter in the Universe, known as the ``baryogenesis" problem, and also,
the so called "Solar Corona Mystery". In this framework, both types of matter (dark and...

It is well known that light scalar fields present during inflation are coherently excited. We show that if the field couples to gravity in a non-minimal way, the fluctuations at large scales are suppressed with respect to the small scales ones. This fact allows for the field excitations to make a sizeable contribution to the energy density of the universe without generating too large...

While the discovery of the Higgs boson at the LHC experimentally confirms the widely successful Standard Model (SM) of particle physics, the theory still falls short of explaining several fundamental features of our Universe. A major shortcoming is the SM’s silence on the nature of Dark Matter (DM). Currently, axions and WIMPs are the leading DM candidates with axions simultaneously addressing...

NA64 is a fixed target experiment at the CERN SPS to search for hidden sectors. In this talk, we will present our latest results on the search for a new sub-GeV vector gauge boson (A′) mediated dark matter (χ) production. The A′, called dark photon, could be generated in the reaction e−Z→e−ZA′ of 100 GeV electrons dumped against an active target which is followed by the prompt invisible decay...

We report on recent results from the PICO program to search for WIMPs using bubble chambers and plans for future experiments. Our most recent results come from the operation of the PICO-60 detector, which operated in the SNOLAB underground laboratory and contained a 52-kg target volume of liquid C3F8 . This chamber exhibits exhibits excellent electron recoil and alpha decay rejection, and the...
