Unveiling the Structure of a Giant Spiral Galaxy with JWST and ALMA Observations Introduction to ADF22.A1 An international team of astronomers used the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/Submillimeter Array (ALMA) to observe the giant spiral galaxy ADF22.A1 . Findings from this study, posted on arXiv on October 29, reveal detailed insights into the galaxy's inner structure. About ADF22.A1: Location and Classification Redshift and Location: Positioned at a redshift on 3.09, ADF22.A1 is a massive barred spiral galaxy within the proto-cluster SSA22. Galaxy Classification: Earlier observations have identified it as a dusty star-forming galaxy (DSFG) with a naturally bright but heavily obscured active galactic nucleus (AGN) . Why ADF22.A1 is Key to Understanding Galaxy Evolution A Laboratory for Understanding Massive Galaxies Astronomers regard ADF22.A1 as a rare laboratory for investigating how massive galaxies and supermassive black holes (SMBHs) ...
