New sample of low-mass black holes in AGN

We present an expanded sample of low-mass black holes (BHs) found in galactic nuclei. Using standard virial mass techniques to estimate BH masses, we select from the Fourth Data...本研究呈现了一批在星系核中发现的低质量黑洞（black holes, BHs）的扩充样本。本研究采用标准位力质量（virial mass）技术估算黑洞质量，从第四批数据（Fourth Data）中筛选出……
