Over the past year, I have used the JSPS KAKENHI Grant to support my research effort for conducting research on the scaling correlation between galaxies and their host galaxies. I performed the analysis using the observation data based on facility including HSC, HST and JWST. Furthermore, I carried out the comparison works using combination of observational and theoretical approaches to understand the origin of the scaling relation. The results of research will be useful to understand their relationships at higher redshift with larger sample. Specifically, I've achieved five publications including the following topics. I carried out a comparative analysis of the scaling relation at 0.2 < z < 1.7 using well-matched observations and multiple state-of-the-art simulations (e.g., Massive-BlackII, Horizon-AGN, Illustris, TNG, and a semianalytic model). Besides, I also analyzed the first light from the JWST observation and measured the host galaxy properties of five quasars with z ~ 1.6-3.5 selected from the Sloan Digital Sky Survey (SDSS) and AEGIS, which fall within the JWST CEERS survey area. We also use 584 SDSS quasars at 0.2 < z < 0.8 with black hole measurements and properties of their hosts from the HSC, aiming at understand how quasars occupy elevated positions from the local M-sigma relation. Overall, my research has made significant contributions to the field of galaxy and host galaxy correlation studies, and has opened up exciting avenues for future exploration.

在过去的一年中，我使用JSP Kakenhi Grant来支持我的研究工作，以研究星系与其宿主星系之间的扩展相关性研究。我使用基于HSC，HST和JWST在内的设施的观察数据进行了分析。此外，我使用观察和理论方法的组合进行了比较工作，以了解缩放关系的起源。研究结果将有助于了解他们在更高的红移中使用较大样本的关系。具体来说，我已经完成了五个出版物，包括以下主题。我使用匹配良好的观测值和多个最新的模拟（例如，巨大的 - 黑色，地平线 - 地平线 - agn，Illustris，tng和一个半分析模型）对0.2 <z <1.7进行了比较分析。此外，我还分析了JWST观察结果的第一个光，并测量了从Sloan Digital Sky Survey（SDSS）和AEGIS中选择的五个类星体的宿主星系性能，该特性属于JWST CEERS调查区域。我们还在0.2 <z <0.8的情况下使用584个SDSS类星体，并使用黑洞测量值及其宿主的特性，旨在了解类星体如何从局部M-Sigma关系中占据升高位置。总体而言，我的研究为银河系和宿主星系相关研究做出了重大贡献，并为将来的探索开辟了令人兴奋的途径。
