The achievements made in the fiscal year of 2019 are summarized as follows: (1) several hundreds of a new and high-resolution optical / near-IR spectra, (2) presentation research at domestic / international conferences, and (3) a publication on the relationship between narrow emission-line ratio and AGN Eddington ratio.(1) We obtained ~200 new optical spectra covering up to near-IR from Palomar, ESO VLT, and SOAR observatory. These new high-resolution spectra are a part of hard X-ray selected AGN, which are what we are currently doing a follow-up optical observations to measure black hole mass, emission-line strengths, and Eddington accretion rates. As a PI and co-I of successful observing programs since 2016, we have been working on observing proposal planning, design, phase 2, data reduction, and spectral line measurements. In addition to the other ~500 optical spectra obtained so far, we are covering complete set of optical spectra of local hard X-ray selected AGN (N~840).(2) We have presented researches in the Korean Astronomical Society meeting (April, 2019) and carried research discussion at the collaboration meeting (ETH Zurich, June 2019). The presentation and discussion were about 1) the recent work about anti-correlation in AGN narrow emission-line ratio and Eddington accretion rate, and 2) a new method estimating / inferring galaxy and AGN spectral features, respectively.(3) A new research work is published in the Astrophysical Journal. We investigated how AGN growth rate is related with narrow emission-line ratios in high-redshift.

2019财年取得的成果总结如下：（1）数百个新的高分辨率光学/近红外光谱，（2）在国内/国际会议上的演示研究，以及（3）关于窄发射线比和AGN爱丁顿比之间关系的出版物。(1)我们从Palomar，ESO VLT和SOAR天文台获得了约200个新的光谱，覆盖近红外。这些新的高分辨率光谱是硬X射线选择AGN的一部分，这是我们目前正在进行的后续光学观测，以测量黑洞质量，发射线强度和爱丁顿吸积率。自2016年以来，作为成功观测计划的PI和co-I，我们一直致力于观测计划的规划，设计，第二阶段，数据简化和谱线测量。除了迄今为止所获得的其他约500个光谱外，我们还包括了局域硬X射线选择活动星系核（N~840）的完整光谱。(2)我们在韩国天文学会会议（2019年4月）上展示了研究成果，并在合作会议（ETH苏黎世，2019年6月）上进行了研究讨论。介绍和讨论了活动星系核窄发射线比和爱丁顿吸积率的反相关研究的最新进展，以及估算和推断星系和活动星系核光谱特征的新方法。(3)一项新的研究成果发表在《天体物理学杂志》上。我们研究了活动星系核的生长速率与高红移下窄发射线比的关系。
