We demonstrate that the emission from faint unresolved satellite sources, $M_{\\rm UV} \\gtrsim -17$, clustered around the central galaxies may play a major role in generating spatially extended Ly$\\alpha$, continuum (${\\rm UV + VIS}$) and H$\\alpha$ halos. We apply the analytic formalism developed in Mas-Ribas & Dijkstra (2016) to model the halos around Lyman Alpha Emitters (LAEs) at $z=3.1$, for several different satellite clustering prescriptions.
