标题： Discovery of three new pulsars in a 610 MHz pulsar survey with the GMRT

摘要： 我们报告了在银河系北平面（45° < l < 135°；|b| < 1°）首次盲搜中发现的三颗新脉冲星，使用的是巨型米波射电望远镜（GMRT）在中间频率610 MHz下的观测结果。 该巡天覆盖了106平方度的面积，对长周期脉冲星（周期大于1秒的脉冲星）的灵敏度约为1毫焦耳每平方米。 这三颗新脉冲星的周期分别为318毫秒、933毫秒和1056毫秒。它们的定时参数和流量密度是在随后使用洛威尔望远镜（位于乔德雷尔班克）和GMRT的观测中获得，并在此报告。 我们还报告了其中一颗新发现的脉冲星PSR J2208+5500的脉冲消没行为。 显示英文摘要

摘要： We report on the discovery of three new pulsars in the first blind survey of the north Galactic plane (45 degrees < l < 135 degrees; |b| < 1 degrees with the Giant Meterwave Radio telescope (GMRT) at an intermediate frequency of 610 MHz. The survey covered 106 square degrees with a sensitivity of roughly 1 mJy to long-period pulsars (pulsars with period longer than 1 s). The three new pulsars have periods of 318, 933, and 1056 ms. Their timing parameters and flux densities, obtained in follow up observations with the Lovell Telescope at Jodrell Bank and the GMRT, are presented. We also report on pulse nulling behaviour in one of the newly discovered pulsars, PSR J2208+5500.
