AbstractUsing the Parkes Radio Telescope, we have carried out deep observations of 11 unassociated gamma-ray sources. Periodicity searches of these data have discovered two millisecond pulsars, PSRJ1103-5403 (1FGLJ1103.9-5355) and PSRJ2241-5236 (1FGLJ2241.9-5236), and a long-period pulsar, PSRJ1604-44 (1FGLJ1604.7-4443). In addition, we searched for but did not detect any radio pulsations from six gamma-ray pulsars discovered by the Fermi satellite to a level of ∼0.04mJy (for pulsars with a 10 per cent duty cycle). The timing of the millisecond pulsar PSRJ1103-5403 has shown that its position is 9 arcmin from the centroid of the gamma-ray source. Since these observations were carried out, independent evidence has shown that 1FGLJ1103.9-5355 is associated with the flat spectrum radio source PKS1101-536. It appears certain that the pulsar is not associated with the gamma-ray source, despite the seemingly low probability of a chance detection of a radio millisecond pulsar. We consider that PSRJ1604-44 is a chance discovery of a weak, long-period pulsar and is unlikely to be associated with 1FGLJ1604.7-4443. PSRJ2241-5236 has a spin period of 2.2ms and orbits a very low mass companion with a 3.5-h orbital period. The relatively high flux density and low dispersion measure of PSRJ2241-5236 make it an excellent candidate for high precision timing experiments. The gamma rays of 1FGLJ2241.9-5236 have a spectrum that is well modelled by a power law with an exponential cut-off, and phase binning with the radio ephemeris results in a multipeaked gamma-ray pulse profile. Observations with Chandra have identified a coincident X-ray source within 0.1 arcsec of the position of the pulsar obtained by radio timing. © 2011 The Authors Monthly Notices of the Royal Astronomical Society © 2011 RAS.
