14:00 Model independent bounds in direct Dark Matter searches

Direct searches for Dark Matter (DM) aim at detecting the nuclear recoils arising from a scattering between DM particles and target nuclei in underground detectors. In this talk, I will first present you a more general approach to study signals in direct DM searches based on non relativistic operators, and then I will review the main observables and the experimental landscape pointing out the main uncertainties that enter in this field. Finally, as the underlying theory that describes both the DM fields and standard model ones is unknown, I will focus on the uncertainties coming from the nature of the interaction. In particular a new framework and a self-contained set of numerical tools to derive the bounds from some current direct detection experiments on virtually any arbitrary model of DM elastically scattering on nuclei will be presented.

16:30 Searching For Dark sub-structure with Gaia

One of the key predictions of Cold Dark Matter (CDM) is the existence of sub-halos at all scales. In order to explain the missing satellite problem many of these sub-halos (in our own galaxy) must be dark- have no or very small stellar component. We have preformed an N-body simulation of the halo and disk of the Milk Way (MW) to study the effect of sub-halos passing through the disk of the galaxy. As a sub-halo passes through the disk of the MW, the sub-halo can leave a wake in the disk potentially detectable with Gaia.
