According to current best estimates, approximately 73% of our Universe is made up of the mysterious "dark energy" component, about one quarter is in the form of cold dark matter (DM), while our familiar baryonic matter makes up less than 5% of the total energy density of the Universe. The existence of DM has so far been inferred only through gravitational means. However, in most of the particle physics models, where DM is thought to be in the form of some unknown elementary particle, the DM particles are often expected to participate also in weak interactions. This leads potentially to a much richer phe- nomenology, and thus also to various new possibilities of detecting DM. The aim of this project is to increase collaboration between particle physicists and cosmologists. The research focus of this study is on DM. We combine the DM theory with the results of cosmological observations and simulations, and with the information on DM from direct and indirect DM detection experiments. Specifically, my research will focus on searching for indirect DM signals from our own Galaxy and for extra-Galactic signals, e.g. from nearby dwarf satellites or from filaments in the large scale structure. These searches require a detailed model (for the dark and luminous components) of our own Galaxy to correctly interpret the observations. This in mind, I will continue to model galaxies, and I will focus on modelling our own Galaxy as accurately as possible. As the majority of the above topics have strong interdisciplinary character, collab- oration with particle physicists and gravitational physicists is of high importance. To this end, I intend to continue my collaboration with Tartu Observatory’s Department of Cosmology, Tuorla Observatory (Finland), and Potsdam Astrophysical Institute (Germany).
