Abstract (from CDS):

We have been conducting the Giant Metrewave Radio Telescope High Resolution Southern Sky (GHRSS) survey for the last four years and have discovered 18 pulsars to date. The GHRSS survey is an off-Galactic-plane survey at 322 MHz in a region of the sky (decl. range -40° to -54°) complementary to other ongoing low-frequency surveys. In this paper we report the discovery of three pulsars (PSRs), J1239-48, J1516-43, and J1726-52. We also present timing solutions for three pulsars previously discovered with the GHRSS survey: PSR J2144-5237, a millisecond pulsar with a period P = 5 ms in a 10 days orbit around a <=0.18 M☉ companion; PSR J1516-43, a mildly recycled P = 36 ms pulsar in a 228 days orbit with a companion of mass ∼0.4 M☉; and the P = 320 ms PSR J0514-4408, which we show is a source of pulsed γ-ray emission. We also report radio polarimetric observations of three of the GHRSS discoveries, PSRs J0418-4154, J0514-4408, and J2144-5237.
