Oral Presentation

Overview of AGN sciences with HSC-SSP and PFS-SSP

Author(s): Yoshiki Toba (Ritsumeikan University), and HSC/PFS-SSP AGN WG

Presenter: Yoshiki Toba (Ritsumeikan University)

The HSC-SSP survey is one of the most powerful imaging surveys to date, enabling us to investigate the statistical and physical properties of AGN across cosmic time. We, the HSC-SSP AGN WG, have published about 90 papers covering broad research topics, such as the statistical properties of quasars in the early Universe, AGN and their host properties, and multi-wavelength and variability-selected AGN.
Building on the success of HSC-SSP, we are now moving toward a detailed investigation of AGN using spectroscopic data from the PFS-SSP. The PFS-SSP AGN WG focuses on spectra obtained from the Cosmology (CO) and Galaxy Evolution (GE) surveys. During the S25A observing run, more than 100,000 sources (including stars and galaxies) were observed, providing a rich dataset for initial analysis. We anticipate obtaining even more spectral data in the upcoming S25B semester.
In this talk, I will first review highlights from HSC-AGN science. I will then report on the current status of AGN observations with PFS-SSP, presenting initial results from the CO and GE fields.
