γ-ray telescopes cannot focus incident high-energy radiation, and the background emission from sources nearby in projection can obscure the periodic emission from pulsars, making unambiguous detection of pulsations difficult. In the context of the Fermi Large Area Telescope (LAT), we present modified statistical tests for periodicity in which each photon is weighted by its probability to have originated from the candidate pulsar. Since the probabilities are calculated using the instrument response function and a full spectral model, they provide powerful background rejection. With Monte Carlo methods, we demonstrate that the new tests increase the sensitivity to pulsars by more than 50% under a wide range of conditions.
