摘要:

目标。通过分析在良好光度条件下用NOT获得的B和R图像,研究了Blazar J 0324 +3410(B20321 +33)宿主星系的性质。方法:采用Sersic模型拟合、非锐化掩模图像、B-R图像和B-R轮廓分析等方法对银河系进行研究。结果:图像显示宿主星系具有环状形态。B-R彩色图像显示了两个蓝色区域:一个与核区域一致,被解释为与活动核相关的发射信号,另一个区域被扩展并位于宿主环结构中。我们讨论的假设,后者是热辐射的恒星形成的相互作用/合并过程中触发的爆发。

英文摘要:

Aims. We investigate the properties of the host galaxy of the blazar J0324+3410 (B2 0321+33) by the analysis of B and R images obtained with the NOT under good photometric conditions. Methods: The galaxy was studied using different methods: Sersic model fitting, unsharp-masked images, B-R image and B-R profile analysis. Results: The images show that the host galaxy has a ring-like morphology. The B-R colour image reveals two bluish zones: one that coincides with the nuclear region, interpreted as the signature of emission related to the active nucleus, the other zone is extended and is located in the host ring-structure. We discuss the hypothesis that the later is thermal emission from a burst of star formation triggered by an interacting/merging process.
