摘要:

在过去的四年里,我们一直在进行GMRT高分辨率南天(GHRSS)调查,迄今为止已经发现了18颗彗星。GHRSS巡天是一次在322 MHz的银河平面外巡天,在天空的一个区域(-40度至-54度的范围)进行,与其他正在进行的低频巡天互补。本文报道了三颗新发现的太阳黑子J1239-48、J1516-43和J1726-52。我们还给出了GHRSS巡天中发现的三颗脉冲星的时间解:PSR J2144-5237,一颗周期为P=5 ms的毫秒脉冲星,在10天的轨道上环绕一颗质量小于0.18 Msun的伴星; PSR J1516-43,一颗周期为P=36 ms的脉冲星,在228天的轨道上环绕一颗质量约为0.4 Msun的伴星; P=320 ms PSR J 0514 -4408是脉冲$γ$射线发射源。我们还报告了三个GHRSS发现,PSR J 0418 -4154,J 0514 -4408和J2144-5237的射电偏振观测。

英文摘要:

We have been conducting the GMRT 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 (declination range -40 degrees to -54 degrees) 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 day orbit around a < 0.18 Msun companion; PSR J1516-43, a mildly recycled P=36 ms pulsar in a 228 day orbit with a companion of mass ~0.4 Msun; 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.
