We have conducted a reprocessing of the Magellanic Clouds survey conducted approximately 20 years ago (Manchester et al. 2006) using the Parkes radio telescope. The initial survey discovered 11 pulsars in the Large Magellanic Cloud (LMC) and 3 in the Small Magellanic Cloud (SMC). Subsequent reprocessing by Ridley et al. (2013) of these archival datasets discovered an additional 5 pulsars in the LMC.
Building on these efforts, we have now reprocessed the survey using more sensitive search techniques based on Sengar et al. (2023, 2025). Our reprocessing has identified 7 new potential pulsars in LMC. Of these, 3 have already been confirmed while the remaining candidates await confirmation. Below are their basic parameters.
