A Search for Radio Emission from the Young 16-ms X-ray Pulsar PSR J0537-6910

Abstract

PSR J0537-6910 is a young, energetic, rotation-powered X-ray pulsar with a spin period of 16 ms located in the Large Magellanic Cloud. We have searched for previously undetected radio pulsations (both giant and standard) from this pulsar in a 12-hour observation taken at 1400 MHz with the Parkes 64-m radio telescope. The very large value of the magnetic field at the light cylinder radius suggests that this pulsar might be emitting giant radio pulses like those seen in other pulsars with similar field strengths. No radio emission of either kind was detected from the pulsar, and we have established an upper limit of ~ 25 mJy kpc^2 for the average 1400-MHz radio luminosity of PSR J0537-6910. The 5-sigma single-pulse detection threshold was ~ 750 mJy for a single 80-us sample. These limits are likely to be the best obtainable until searches with greatly improved sensitivity can be made with next-generation radio instruments.
