近日，我院天体物理张雪光团组在天文学著名期刊《MNRAS》上发表了题为“在1.9型活动星系中基于双峰宽发射线对中心尘埃环张角测量的可行性mgm 바카라 실시간”（A practicable method to estimate opening angle of central dust torus in type-1.9 AGN with double-peaked broad Hα）的mgm 바카라 실시간性文章。

在该项工作中，我们成功地提出了使用Type-1.9活动星系核中的双峰宽发射线的独特特征，在考量吸积盘起源的大前提下，使用吸积盘的倾角完成了对活动星系核中心尘埃环张角的初步标定。该方法不同于传统的基于统计结果对尘埃环张角的论证，可以在个源Type-1.9的具有双峰宽发射线的活动星系核中完成尘埃环张角的测量核标定，为进一步进行mgm 바카라 실시간尘埃环空间特性对活动星系核中心物理特征的依赖打下了坚实的基础，从而成为我们下一步要系统进行的活动星系核尘埃环特性的mgm 바카라 실시간提供了理论基础，我们将在该mgm 바카라 실시간的基础上，完成一个系列的关于活动星系核尘埃环特性讨论的文章。

Fig. 1:Top panels show mgm 바카라 실시간 best fitting results (solid red line) to mgm 바카라 실시간 emission lines (solid dark green line), and bottom panels show mgm 바카라 실시간 corresponding residuals. In top left panel, solid blue line shows mgm 바카라 실시간 determined narrow H$\beta$, solid green lines show mgm 바카라 실시간 determined [OIII] doublet. In top right panel, solid blue line shows mgm 바카라 실시간 determined narrow Hα, solid cyan line shows mgm 바카라 실시간 determined double-peaked broad Hα described by mgm 바카라 실시간 elliptical accretion disk model, solid green lines show mgm 바카라 실시간 determined [OI], [NII] and [SII] doublets, dashed purple lines show mgm 바카라 실시간 determined broad Hα described by two broad Gaussian functions. In each bottom panel, horizontal dashed mgm 바카라 실시간s show residuals=0,±1, respectively.
