NVSS and FIRST variable sources

In the present study we have cross-correlated NVSS and FIRST radio catalogues having radio flux measurements at the same 1.4GHz frequency. This way we benefit from repeated...本研究中，我们对均包含1.4吉赫频率射电流量测量数据的NVSS（NRAO VLA Sky Survey，甚大阵射电巡天）与FIRST（Faint Images of the Radio Sky at Twenty-Centimeters，二十厘米射电天空弱源图像巡天）射电目录开展了交叉关联分析。通过此种方式，我们可获益于重复的……
