论文摘要
SDSS J163401.94 $+$+$ 480940.2是一种未射击的无线电窄线Seyfert 1(NLSY1)Galaxy。该对象的光学监视是在两个$ \ geq $ 3 hrs的两个$ 360万点的$ \ geq $ \ geq进行的。该来源首次提出了夜晚的光学变异性(INOV)表征。在两个监控SDSS的一次监控之一中,我们发现了一个引人注目的爆发,$+$+$+$ 480940.2,其快速亮点阶段暗示了一分钟,例如$ \ sim $ \ sim $ 22分钟,从而接近了非常快速的分钟类似的可变性,从FSRQ PKS 1222222222222222222222220AT 400 gat at 400 gat at 400 cat at 400 00 g ev中观察到。检测细分量的变异性表明存在相对论的喷气机,其视角很小。我们简要讨论了相对论喷气机在其很长的基线阵列(VLBA)观察结果中的可能机制。
SDSS J163401.94$+$480940.2 is a non-jetted radio-loud narrow-line Seyfert 1 (NLSy1) galaxy. Optical monitoring of this object was carried out in two intra-night sessions each $\geq$ 3 hrs with 3.6m DOT. Intra-night optical variability (INOV) characterization is presented for the first time for this source. We have detected an unexpected remarkable flare in one of two monitoring sessions of SDSS J163401.94$+$480940.2, whose rapid brightening phase implied a minute like doubling time of $\sim$ 22 minutes, thereby approaching to the extremely fast minute like variability, observed from FSRQ PKS 1222$+$21 at 400 GeV. The detection of a minute-like variability suggests the existence of relativistic jets with a small viewing angle. We briefly discuss the possible mechanisms for the non-detection of relativistic jets in its Very Long Baseline Array (VLBA) observations.
