In this paper, we investigate radio properties of active galaxies taken from the reference [Véron‐Cetty & Véron (2010)] catalog. The galaxies are limited to magnitudes in the range of 12^m − 19^m. We have cross‐correlated the list with radio catalogs and selected those galaxies that have data on six or more radio fluxes at different wavelengths. As a result, we have 198 galaxies that satisfy these conditions. Using SDSS DR15, we have obtained 96 spectroscopic identifications of the 198 objects. After the classification, 85% of the 96 objects have changed their types. Available data on the classification of these objects and our classification showed that 56.7% of them are Seyfert galaxies. For all the objects, we have built radio spectra and estimated radio spectral indices. As a result, we obtain , , , ). We discuss the radio properties of active galaxies based on their radio spectral indices.

主动星系的性质，基于它们的无线电特性

在本文中，我们研究了从参考书目[Véron-Cetty＆Véron（2010）]中获取的活跃星系的无线电特性。星系限制在12 ^m  − 19 ^m范围内。我们将该列表与无线电目录进行了互相关，并选择了具有六个或更多不同波长的无线电通量数据的星系。结果，我们有198个满足这些条件的星系。使用SDSS DR15，我们获得了198个物体的96个光谱识别。分类后，96个对象中的85％已更改其类型。关于这些物体分类的可用数据以及我们的分类显示，其中56.7％是塞弗特星系。对于所有对象，我们已经建立了无线电频谱和估计的无线电频谱指数。其结果是，我们得到，，，）。我们根据活动星系的无线电频谱指数讨论它们的无线电特性。
