我院天体物理光学AGN团组在天文学期刊《MNRAS Letters》上发表了题为“SDSS J1619 with blue-shifted broad components in Hα and in [OIII] having similar line width and velocity shifts: a recoiling SMBH candidate?”的SCI文章。
在该项工作中,考虑到recoiling BH可以运动到NLRs的基本预期,将会同时对宽发射线和窄发射线比产生影响,在SDSS J1619中的Hα和[OIII]发射线中首次发现了具有相同蓝移速度和相同速度展宽的成分,预示着recoiling BH 不仅贯穿了BLRs,且运动到了NLRs的内部近邻区域,为贯穿的recoiling BH提供了有趣切充实的证据。为以后进行类似工作的样本性研究提供了基础。

Fig. 1: On the best fitting results to the emission lines around Hβ (left panel) and Hα (right panel). In the left panel, solid dark green lines show the broad blue-shifted components in [OIII] doublet, solid blue line shows the determined broad blue-shifted component in Hβ. In the right panel, solid blue line shows the determined broad blue-shifted component in Hα.
