Optical spectral atlas of Seyfert nuclei

We present an optical spectral atlas of the nuclear region (generally 2"x4", or r=<200pc) of a magnitude-limited survey of 486 nearby galaxies having B_T_=<12.5mag and...我们呈现了一项星等限制巡天的光学光谱图集，该巡天共纳入486个总B星等（B_T）≤12.5星等的近邻星系，图集的观测覆盖范围为星系核区（通常为2角秒×4角秒，对应径向距离r≤200秒差距），且……
