Active Galactic Nuclei Science Interest GroupWe invite everyone to join us for the inaugural AGN SIG Spotlight Talk on Tuesday, January 27, 2026, at 1 pm ET/10 am PT. Our kickoff session will feature two invited talks by Dr. Namrata Roy (University of Arizona) and Dr. Lulu Zhang (University of Texas at San Antonio), who will share their latest work. This opening session will set the stage for the Spotlight and Vision series and mark the beginning of regular monthly AGN SIG events in 2026.

Turning a New Page in the AGN Feedback Chapter: Mapping Multiphase AGN Feedback from Powerful Jets to Weak Winds
Speaker
Dr. Namrata Roy (Arizona State University)
Abstract
Active Galactic Nuclei (AGNs) are the most energetic phenomena in the universe, driving feedback through jets, multiphase outflows, and intense radiation. I will present a new chapter in our understanding of AGN feedback, showcasing recent breakthroughs from JWST, and spatially resolved spectroscopy. I will connect two seemingly extreme regimes: monstrous radio jets in the early Universe and weak “maintenance-mode” AGNs today, to demonstrate how feedback couples to gas across the ISM–CGM interface in various regimes. I will first show that High-redshift radio galaxies (HzRGs) within the first billion years after the Big Bang are uniquely powerful laboratories. Using JWST IFU data, I will highlight that these jets pierce through the surrounding gas, inflate enormous cocoons of shocked gas, and launch fast outflows in the ionized phase. I will present spatially resolved empirical constraints on mass, momentum, and energy flow rates a …
