摘要
使用上海天文台 1.5 6m望远镜 ,对窄线赛弗特 1星系Ark 5 6 4进行了时间跨度为 3星期的观测 ,给出了VRI波段的光学观测结果。使用交叉相关方法研究了三个波段之间的时间延迟 。
A 3weekmonitoring for the Narrowline Seyfert 1 galaxy Ark 564 was carried out by the 1.56m telescope of Shanghai Astronomical Observatory. The light curves of V, R and I bands are presented. No time lags between these bands were detected by the crosscorrelation function.
