Show affiliationsThe supernova remnant G0.9+0.1 has long been inferred to contain a central energetic pulsar. In observations with the NRAO Green Bank Telescope at 2 GHz, we have detected radio pulsations from PSR J1747–2809. The pulsar has a rotation period of 52 ms, and a spin-down luminosity of 
erg s–1, the second largest among known Galactic pulsars. With a dispersion measure of DM = 1133 pc cm–3, PSR J1747–2809 is distant, at 
13 kpc according to the NE2001 electron density model, although it could be located as close as the Galactic center. The pulse profile is greatly scatter-broadened at a frequency of 2 GHz, so that it is effectively undetectable at 1.4 GHz, and is very faint, with period-averaged flux density of 40 μJy at 2 GHz.
