Abstract: The Galactic halo is well populated by tidal streams and overdensities, showing its heterogeneus origin and providing important clues about its formation history. RR Lyrae stars have proven to be excellent tracers of halo substructures, due to the quality of the distances that can be derived from them, and the relatively straightforward methods that lead to their clean identification. In this work, we present our observational efforts to unveil and characterize the hypothetical accreted systems in areas of the sky with an evident excess of RR Lyrae stars. In particular, we have focused in the southern hemisphere, where some of these substructures seem to be connected with other northern stellar halo substructures.
