Multiphase images of a powerful supernova-driven wind in the early Universe
Rebecca L. Davies, D. B. Fisher, R. Herrera-Camus +38
Galactic winds are considered a likely driver of rapid quenching in early massive galaxies, but until now there has been no direct evidence that such systems drive winds powerful e…

Mai Liao, Roberto J. Assef, Chao-Wei Tsai +17
Supermassive black holes (SMBHs) imprint gravitational signatures on the matter within their sphere of influence (SoI). Nuclear gas dynamics can hence be used to accurately measure…

A hidden active galactic nucleus powering bright [O III] nebulae in a protocluster at revealed by JWST
M. Solimano, J. González-López, M. Aravena +48
Galaxy protoclusters are sites of rapid growth, with a high density of massive galaxies driving elevated rates of star formation and accretion onto supermassive black holes. Here,…

Primordial Rotating Disk Composed of 15 Dense Star-Forming Clumps at Cosmic Dawn
S. Fujimoto, M. Ouchi, K. Kohno +43
Early galaxy formation, initiated by the dark matter and gas assembly, evolves through frequent mergers and feedback processes into dynamically hot, chaotic structures. In contrast…
A lack of LAEs within 5Mpc of a luminous quasar in an overdensity at z=6.9: potential evidence of quasar negative feedback at protocluster scales
Trystan S. Lambert, R. J. Assef, C. Mazzucchelli +13
High-redshift quasars are thought to live in the densest regions of space which should be made evident by an overdensity of galaxies around them. However, campaigns to identify the…
