Origin of nuclear activity in low-power radio galaxies

Using large samples containing nearly 2300 active galaxies of low radio luminosity (1.4 GHz luminosity between 2x10^23^ and 3x10^25^ W/Hz, essentially low-excitation radio...本数据集使用包含近2300个低射电光度活动星系（active galaxies）的大样本，其1.4 GHz射电光度介于2×10²³ 至 3×10²⁵ W/Hz之间，本质上属于低激发射电
