An L-band (ALFA) Search for Giant Pulses from M33

We propose to conduct a systematic search of the M33 galaxy with ALFA for potential bright giant pulses from Crab-like pulsars. We will exploit ALFA's multibeam capability for both large instantaneous coverage as well as efficient identification and elimination of false positives that may result from sporadic radio-frequency interference (RFI). The ALFA system, with its high sensitivity and wide-bandwidth, will be capable of detecting bright giant pulses (GPs) from Crab-like pulsars in M33 (for instance, Crab GPs of peak flux densities 2 в 104 Jy are detectable with S/N 5 at M33's distance). In addition to important science goals that will be enabled by the potential discoveries of pulsars in the galaxy (e.g. studies of pulsar population and ISM in the galaxy, and probing the IGM), the algorithms and methodology that we develop will also be applicable to science planned with next-generation radio arrays (including the SKA), particularly searching for fast transients in the radio sky.
