Outline of Research at the Start

In FY2022, I will carry out the comparison work between HSC observation (that has been analyzed using AGN+host) and the state-of-art simualtion. I will get one refereed journal paper published. I will also develop the image modeling tool and use simulation to test on the model of HSC QSO (for host disk+bulge decomposition) and JWST QSO (for AGN+host analyze).
In FY2023, I plan to analyze the HSC sample and JWST sample and summarize the research work and submit the paper to journals.
In FY2024, I plan to make comparsion with numerical simulations using the updated observation result and compare.

Outline of Annual Research Achievements

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.

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

I consider a smooth progress that I've made over the past year on the scaling correlation between galaxies and their host galaxies. By utilizing a combination of observational and theoretical approaches, I have gained a better understanding of the origin of this relation. The outcomes of my research are evidenced by the several publications that have resulted from it, including a comparative analysis of the scaling relation at different redshifts, as well as an analysis of the host galaxy properties of quasars, using data from HSC, HST and JWST. These findings are significant because they improve our knowledge of the relationships between galaxies and their host galaxies at higher redshifts, and shed light on the mechanism that explains why quasars occupy elevated positions from the local M-sigma relation. Additionally, the achievements of the past year have set a strong foundation for my upcoming research activities.

Strategy for Future Research Activity

For the upcoming year, I plan to continue my research effort and utilize the newly discovered high-z AGNs by HSC and the capabilities of JWST to perform the deep analysis of the AGN host bulge and understand the scaling relation. Additionally, I will incorporate more high-z AGNs into the study. I will using my HST grism data to confirm the nature of 11 dual AGN candidates. These sample will be used to answer how galaxy mergers influence the evolution of AGNs and galaxies, especially during the final coalescence stage, and use ALMA to investigate the fueling process. To understand the theoretical model, I will use the state-of-the-art hydrodynamical simulations to make a direct comparison with our newly measured high-z data. I will use the z~6 quasar host measurement based on JWST to test with the simulation using the scaling relation between BH mass and stellar mass, galaxy size-mass relation, and the galaxy morphology comparison. Such a comparative analysis will be crucial to verify the assumptions adopted in the simulation.
