摘要:

使用伽马射线数据收集的Astronivelatore伽马广告Immagini LEggero(AGILE)卫星在近一年的时间内(从2007年7月至2008年6月),我们寻找脉冲信号从35个潜在的有趣的无线电天文台,根据$F_γ\propto \sqrt{\dot{E}} d^{-2}$和当代或最近的无线电数据。AGILE通过时间和空间分析检测到了三个新的顶级附近和Vela类天体,具有良好的信心。在新发现的恒星中,我们发现了具有非常高的旋转能量损失的恒星,例如具有超过10^13高斯的磁场的引人注目的PSR B 1509 -58,以及PSR J2229+6114,它为先前未被识别的EGRET源3EG 227 +6122提供了可靠的识别。此外,球状星团M28中的强大毫秒脉冲星B1821-24在一小部分观测中被探测到。其他四颗有希望的伽马射线脉冲星候选者,其中包括着名的J2043+2740,其年龄超过100万年,仅在时序分析中显示可能的检测,值得确认。

英文摘要:

Using gamma-ray data collected by the Astrorivelatore Gamma ad Immagini LEggero (AGILE) satellite over a period of almost one year (from 2007 July to 2008 June), we searched for pulsed signals from 35 potentially interesting radio pulsars, ordered according to $F_γ\propto \sqrt{\dot{E}} d^{-2}$ and for which contemporary or recent radio data were available. AGILE detected three new top-ranking nearby and Vela-like pulsars with good confidence both through timing and spatial analysis. Among the newcomers we find pulsars with very high rotational energy losses, such as the remarkable PSR B1509-58 with a magnetic field in excess of 10^13 Gauss, and PSR J2229+6114 providing a reliable identification for the previously unidentified EGRET source 3EG 2227+6122. Moreover, the powerful millisecond pulsar B1821-24, in the globular cluster M28, is detected during a fraction of the observations. Four other promising gamma-ray pulsar candidates, among which is the notable J2043+2740 with an age in excess of 1 million years, show a possible detection in the timing analysis only and deserve confirmation.
