空间调制搜索在FAST高闪烁脉冲星搜索和确认中的应用及在M3发现的一颗脉冲星

Spatial Modulation Search Applied to the Search and Confirmation of Highly Scintillated Pulsars at FAST with A Pulsar Discovered in M3

Lei Qian, Zhichen Pan

摘要:

提出了一种基于脉冲星搜索观测中位置切换模式的脉冲星候选者识别和确认方法。该方法利用脉冲星信号的不同空间特征和射频干扰(RFI),在一次观测中实现了脉冲星的同时搜索和确认。基于这种方法,我们在球状星团M3、M15和M92中进行了脉冲星搜索观测。我们发现并确认了一颗新的脉冲星M3F,并探测到了已知的脉冲星M3B、M15 A至G(C除外)和M92 A。

英文摘要:

We present a pulsar candidate identification and confirmation procedure based on a position-switch mode during the pulsar search observations. This method enables the simultaneous search and confirmation of a pulsar in a single observation, by utilizing the different spatial features of a pulsar signal and a radio frequency interference (RFI). Based on this method, we performed test pulsar search observations in globular clusters M3, M15, and M92. We discovered and confirmed a new pulsar, M3F, and detected the known pulsars M3B, M15 A to G (except C), and M92A.
