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.
