研究実績の概要

We are determining whether the mass ratio between supermassive black holes and their host galaxies is constant out to the early Universe. This is achieved through a James Webb Space Telescope program that targets 12 SHELLQs quasars at z ~ 6 from the HSC Subaru Strategic Program. We are determining the (1) masses of quasar host galaxies, (2) their black hole masses, and (3) the distribution of black hole mass and Eddington rate, all key to understanding the growth of SMBHs. Including a study of SMBHs at later cosmic times with COSMOS-Web, a large JWST imaging survey, we are constructing a full picture of the growth of galaxies and their black holes. In FY 2023, we published in Nature the results on the first two host detections and stellar mass estimates.

理由

In FY 2023, we have received and analyzed the JWST data (NIRCam and NIRSpec) for an additional eight (10 of 12 in total) SHELLQs quasars at z ~ 6 which have been processed for science-grade measurements. With this larger sample, we significantly detect the host galaxies for seven targets and the broad emission lines with NIRSpec which provide black hole masses. We are actively working on the analysis of the full sample and preparing publications. In addition, we have successfully analyzed 104 AGN in the COSMOS-Web NIRCam survey by running our 2D image decomposition tool which results in a robust measure of the ratio between black holes mass and the stellar mass of their host galaxies out to z~3. This work has been submitted to the Astrophysical Journal for publication.

今後の研究の推進方策

We are continuing with the planned research program. We will complete the studies on the following: (1) the relation between black hole and galaxy mass, (2) constraints on the black hole mass function and Eddington rate distribution, (3) stellar populations of quasar host galaxies at z~6 and (4) the importance of gas content in the early Universe. We are finalizing our decomposition of 104 quasars up to z ~ 3 into separate quasar and host galaxy light with COSMOS-Web. Follow up proposals to JWST and ALMA will be submitted to study in detail their stellar populations, gas content and large-scale environments. Coupled with the Hyper Suprime-Cam Subaru Strategic Survey, we will present a comprehensive picture of black hole and galaxy growth using the SHELLQs and COSMOS-Web programs.
