论文摘要

Galaxy Centers中的中间质量黑洞(IMBHS; $ M_ {BH} <2*10^{5} M _ {\ odot} $)是cr tr依tr tr,用于绘制超级及格黑洞(SMBHS)的形成和成长的连贯形态和成长的一致图片。使用大数据分析,我们确定了IMBH的305个IMBH候选者和1623个``轻量''SMBHS($ 2 * 10^{5} M_ {odot} <m_ {odot} <m_ {bh} <10^{6} <10^{6} m_ {\ odot} $)。对于来自该组合样品的35个宿主星系,并使用X射线确认的活性银河核(AGN),我们收集并分析了光谱观测。这些数据表明,膨胀恒星速度分散($σ_*$)在24美元的范围内$ 118〜 km/s,并且不遵循与$ M_ {BH} $建立的较大SMBHS建立的相关性 渠道。

Intermediate-mass black holes (IMBHs; $M_{BH} <2*10^{5} M_{\odot}$) in galaxy centers are cruciel for painting a coherent picture of the formation and growth of supermassive black holes (SMBHs). Using Big Data analysis, we identified 305 IMBH candidates for IMBH and 1623 candidates of `light-weight' SMBHs ($2 * 10^{5} M_{odot} < M_{BH} <10^{6} M_{\odot}$). For 35 host galaxies from this combined sample with the X-ray-confirmed active galactic nuclei (AGN) we collected and analyzed optical spectroscopic observations. These data show that bulge stellar velocity dispersions ($σ_*$) lie in the range of 24$\dots$118~km/s and do not follow the correlation with $M_{BH}$ established by larger SMBHs indicating that in the $10^{5}-10^{6} M_{\odot}$ range the accretion is the prevailing BH growth channel.
