Broad H{beta} emission line in 102 Seyfert galaxies

A sample of 102 local (0.02=<z=<0.1) Seyfert galaxies with black hole masses M_BH_>10^7^M_{sun} was selected from the Sloan Digital Sky Survey (SDSS) and observed using...从斯隆数字巡天（Sloan Digital Sky Survey, SDSS）中选取了102个红移z满足0.02≤z≤0.1的本地赛弗特星系样本，其黑洞质量M_BH大于10^7倍太阳质量，并使用……开展观测。
