Abstract (from CDS):

We report the discovery with the 100 m Green Bank Telescope of 65 ms radio pulsations from the X-ray pulsar J0205+6449 at the center of supernova remnant 3C 58, making this possibly the youngest radio pulsar known. From our observations at frequencies of 820 and 1375 MHz, the free-electron column density to PSR J0205+6449 is found to be 140.7±0.3 cm–3.pc. The barycentric pulsar period P and period derivative P{dot} determined from a phase-coherent timing solution are consistent with the values previously measured from X-ray observations. The averaged radio profile of PSR J0205+6449 consists of one sharp pulse of width ~3 ms ~ 0.05P. The pulsar is an exceedingly weak radio source, with a pulse-averaged flux density in the 1400 MHz band of ∼45 µJy and a spectral index of ~-2.1. Its radio luminosity of ∼0.5 mJy.kpc2 at 1400 MHz is lower than that of ∼99% of known pulsars and is the lowest among known young pulsars.
