AGN SIG Spotlight Series, 18 Aug 2026
AGN SIG Spotlight Series. Speakers: Dr. Xiaojing Lin (Tsinghua University) and Dr. Pallavi Patil (National Radio Astronomy Observatory) The post AGN SIG Spotlight Series, 18 Aug 2026 appeared first on NASA Science .
The AGN SIG Spotlight Series, hosted on 18 August 2026 in a virtual setting, brought together two prominent speakers in the field of high-redshift astronomy. Dr. Xiaojing Lin from Tsinghua University delivered a seminar titled "Probing the Early Growth of Black Holes through Low-ReDshift LRD Survey ((LRDs)²)." In her presentation, Dr. Lin explored the challenges posed by Little Red Dots (LRDs), which were identified by the James Webb Space Telescope at redshifts around 4.
These LRDs have sparked debate about their physical nature, as they challenge existing frameworks for black hole growth and active galactic nucleus (AGN) evolution.
The second speaker, Dr. Pallavi Patil from the National Radio Astronomy Observatory, presented a seminar titled "Unveiling the Role of AGN in Post-Starburst Galaxies: Quenching Mechanisms at Cosmic Noon." Post-starburst galaxies (PSBs), which have recently undergone a massive starburst, are increasingly common at redshifts between 0.5 and 1-2.
These galaxies may play a significant role in the growth of the red sequence observed in the local Universe. Dr. Patil's research focuses on the role of AGN feedback in shutting down star formation in PSBs and driving their evolution from star-forming to quiescent states.
