JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon
Chloë E. Benton, Erica J. Nelson, Tim B. Miller +10
Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon -- the peak of cosmic star formation history -- appear disk-dominated, leaving the origin of the…

AGN Feedback in Quiescent Galaxies at Cosmic Noon Traced by Ionized Gas Emission
Letizia Bugiani, Sirio Belli, Minjung Park +17
We analyze ionized gas emission lines in deep rest-frame optical spectra of 16 quiescent galaxies at redshift observed with JWST/NIRSpec by the Blue Jay survey. Robust…
