JADES — The Rosetta Stone of JWST-discovered AGN: deciphering the intriguing nature of early AGN

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ignas Juodžbalis, Xihan Ji, Roberto Maiolino, Francesco D’Eugenio, Jan Scholtz | Summary: JWST has discovered a large population of Active Galactic Nuclei (AGN) at high redshift. Many of these newly discovered AGN have broad permitted lines (typically H$alpha$), but are extremely weak in the X-rays. Here we […]
