    Are the extended narrow line regions in AGN photoionized by the emission from thick accretion disks?
    We study the photoionization of the Extended Narrow Line Region (ENLR) using three anisotropic radiation fields: (1) a geometrically thick accretion disk; (2) a...

    CEERS Key Paper. VI. JWST/MIRI Uncovers a Large Population of Obscured AGN at High Redshifts
    Mid-infrared (mid-IR) observations are powerful in identifying heavily obscured active galactic nuclei (AGN) that have weak emission in other wavelengths. Data...
