论文摘要
我们报告确定新的伽马射线发射狭窄的Seyfert 1 Galaxy（γ-NLS1），SDSS J095909.51+460014.3（Z = 0.399），通过与伽马 - 射线来源4FGL 0959.6+4606，尽管与少量的by to to to to to to to to to to to to to to to y-by y-bor-y-nory waysy to an J09591976+4603515。这两种来源的明智的长期光曲线揭示了各种红外变异性模式。对于以前的来源，检测到2.5 mag的亮度，而另一个磁磁则衰减为0.5 mag。更重要的是，NLS1的红外通量升高的时间与4FGL 0959.6+4606的通量增加的时间相吻合。同时，尚未观察到射电星系的红外活动。针对高γ射线通量状态的15个月费米LAT数据的特定分析可产生重要的来源（TS = 43）。相应的伽马射线定位分析表明，只有NLS1落入不确定性区域，进一步支持更新的关联关系。 SDSS J095909.51+460014.3的宽带光谱能量分布已被经典的单区均质Leptonic Jet模型绘制并很好地描述。研究了其喷气性能，并发现与已知的伽马NLS1相比。
We report on an identification of a new gamma-ray emitting narrow-line Seyfert 1 galaxy (gamma-NLS1), SDSS J095909.51+460014.3 (z = 0.399), by establishing an association with a gamma-ray source 4FGL 0959.6+4606, although its low-energy counterpart was suggested to be a radio galaxy 2MASX J09591976+4603515. WISE long-term light curves of these two sources reveal diverse infrared variability patterns. Brightenings of 2.5 mag are detected for the former source, while flux decays of 0.5 mag are found for the other one. More importantly, the time that the infrared flux of the NLS1 rises, is coincident with the time of flux increase of 4FGL 0959.6+4606. At the same time, no infrared activity of the radio galaxy has been observed. A specific analysis of 15-month Fermi-LAT data, aiming at the high gamma-ray flux state, yields a significant source (TS =43). The corresponding gamma-ray localization analysis suggests that only the NLS1 falls into the uncertainty area, further supporting the updated association relationship. A broadband spectral energy distribution of SDSS J095909.51+460014.3 has been drawn and well described by the classic single-zone homogeneous leptonic jet model. Its jet properties are investigated and found to be comparable with the known gamma-NLS1s.
