Gravitational accretion of dark matter in neutron stars may constitute a mechanism to check for further indirect effects of its existence. In this way, dark matter annihilations taking place within such compact astrophysical objects may prevent the appearance of additional particle population of hadrons inside the neutron star core. We discuss on the experimental consequences of this possibility.

With the advent of low-threshold detectors that look for neutrino scattering at sub-keV energy deposition, the sensitivity to possible neutrino electromagnetic moments can be further increased. As such low energies start to overlap with atomic scales, it is necessary to take atomic binding effects into account so that detector responses can be understood more reliably. In this talk, we present...
