Previrialized Assembly at Cosmic Dawn: The Dynamics and Extreme Ionization of Compact Group CGG-z7 at z ∼ 7.04
We report the discovery of CGG-z7, the most compact galaxy group at z ≳ 7 identified to the north of the GOODS-North field, observed by the JWST POPPIES program. The system consists of at least six members within a projected size of 7.8 × 5.7 kpc ^2 , four of which are spectroscopically confirmed v...
