A Search for H and H[O III] Dual-Line Emitting Galaxies in the JWST CEERS Field: Implications for the AGN Abundance
Jingsong Guo, Masafusa Onoue, Kohei Inayoshi +4
The James Webb Space Telescope (JWST) has enabled us to uncover faint galaxies and active galactic nuclei (AGNs) in the early universe. Taking advantage of the unique filter combin…
