Software data-processing pipeline for transient detection

Abstract

Although several existing and upcoming telescopes have imaging as their primary mode, they also have a sensitive phased-array mode with a multiple-beam forming capability enabling high time resolution studies of several types of objects, including pulsars. For example, the potentially wide coverage in frequency, combined with its collecting area, makes the MWA-LFD a unique instrument for low-frequency detection and studies of pulsars and transients. A software data-processing pipeline is being developed by the Raman Research Institute for this purpose. We describe the various issues relevant to the detection strategies, illustrated with real data at low radio frequencies.
