High-Resolution Pulsar and Transient Survey of the LMC

Scientific Motivation and Goals

The high-resolution survey of the LMC for pulsars is motivated by several science goals. These goals include:

  • Exploring the star formation and environmental differences between the LMC and the Milky Way.
  • Determining the effect of low metallicity on stellar winds from non-degenerate pulsar companions.
  • Obtaining a complete sample of binary radio pulsar systems in the LMC.
  • Discovering new members of different neutron star populations in the LMC.
  • Probing the high end of the pulsar luminosity function.
