Understanding the growth of low-mass black holes and its role in galaxy evolution

2019年财政年度取得的成就概括如下：(1)数百个新的高分辨率光学/近红外光谱，(2)在国内/国际会议上的演讲研究，(3)关于窄发射线比与活动星系核-爱丁顿比关系的出版物。(1)我们从Palomar、ESO VLT和SOAR天文台获得了覆盖近红外的近200个新光谱。这些新的高分辨率光谱是硬X射线选择的活动星系核的一部分，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，作为成功观测项目的PI和COI，我们一直致力于观测方案的规划、设计、第二阶段、数据简化和谱线测量。除了到目前为止获得的其他~500个光谱外，我们还覆盖了本地硬X射线选择的活动星系核(N~840)的全套光谱。(2)我们在韩国天文学会会议(2019年4月)上介绍了研究成果，并在合作会议(2019年6月苏黎世ETH)上进行了研究讨论。介绍和讨论了活动星系核窄线比和爱丁顿吸积率反相关的最新工作，以及估计/推断星系和活动星系核光谱特征的新方法。(3)一项新的研究工作发表在《天体物理杂志》上。我们研究了在高红移条件下活动星系核的生长速率与窄的发射线比之间的关系。

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.
