Supermassive Black Holes, Feedback and Galaxy Evolution
The IAU Commission X1 is a Cross-Division D-J initiative with the primary goal of promoting the development of research on supermassive black holes (SMBHs), active galactic nuclei (AGNs) and star formation feedback, as well as their role in galaxy evolution.
Through this commission, we aim to foster interaction between theorists and observers across the electromagnetic spectrum to investigate the interplay between the growth of SMBHs and galaxies, including the effects of their environment.
We aim to bridge the studies on feedback from the “galaxy evolution" community, which primarily focuses mostly on the role of star formation, and the “AGN" community, which concentrates on feedback from the environments of the nuclear SMBH, in order to advance our understanding of galaxy evolution.
We welcome input from the community to enhance our initiatives and collaborations. Please share your feedback by completing this form
This Quasar May Have Helped Turn the Lights on for the Universe
The newly discovered quasar J1429+5447 in the early universe, with its rapid X-ray brightening, reveals a powerful jet pointed toward Earth. This rare finding provides key insights into reionization and the mysterious growth of supermassive black holes.
