摘要:

本文给出了Seyfert星系Mrk 79和NGC5548的Johnson-BVRI表面亮度剖面分解的初步结果。的配置文件被建模为高斯法律的核,Sersic法律的凸起和指数法的磁盘的总和。在Mrk 79的模型轮廓中添加了一个扁杆。导出了各结构分量的参数和总幅值。

英文摘要:

We present preliminary results of the Johnson-Cousins (U)BVRI surface brightness profile decompositions of the Seyfert galaxies Mrk 79 and NGC 5548. The profiles were modelled as a sum of a Gaussian law for the nucleus, a Sersic law for the bulge and an exponent law for the disk. A flat bar was added to the model profile of Mrk 79. The parameters and the total magnitudes of the structural components were derived.
