In our concordance cosmology, large galaxies assemble through multiple mergers of smaller galaxies. During this process, tidal forces strip loosely bound stars, leaving imprints of these interactions in the form of a faint and diffuse stellar envelope around galaxies, which holds important information about their assembly histories. In this thesis, I study this Intra-Halo Stellar Component using state-of-the-art cosmological hydrodynamical simulations of galaxy formation. The goal is to understand the physical mechanisms that shape its abundance and properties across entire galaxy populations.
