Abstract: The existence of dark matter suggests the presence of an extended dark sector that is neutral under all standard-model forces. This hidden sector could be extremely simple and minimal but it might as well conceal a rich and intricate structure with matter and forces of its own. The search of observational tests of the dark sector is a new and rapidly expanding field of research. It offers new insights on the long-standing problem of DM and the role played by it in cosmology and structure formation. Experimental tests are already being deployed, and more will be in the near future. The aim of this research project is to propose and explore observational tests of the dark sector by following as much as possible new unexplored lines of investigations. In particular, covering the possibility that this new sector be truly dark and interacting with ordinary matter only gravitationally.

Description: We provide a detailed description of the project in the attached file "Dark_Sector.pdf".
