We report our progress in the study of collective scattering effects with ultracold atoms coupled to a high-finesse optical resonator. In order to observe collective scattering from the side into the resonator, we trap up to 104 rubidium atoms in a deep two-dimensional optical lattice with a lattice spacing of the wavelength of the scattered light. In this setup, all atoms are coupled identically to the resonator and light scattered into the resonator by individual atoms interferes constructively. In addition, high trapping frequencies with respect to the resonator linewidth allow us to study cavity cooling.
