Strong spectral features from asymptotic giant branch stars in distant quiescent galaxies
Shiying Lu, Emanuele Daddi, Claudia Maraston +27
Dating the ages and weighting the stellar populations in galaxies are essential steps when studying galaxy formation through cosmic times. Evolutionary population synthesis models…
Characterizing the Average Interstellar Medium Conditions of Galaxies at 5.6-9 with UV and Optical Nebular Lines
Weida Hu, Casey Papovich, Mark Dickinson +30

We present a sample of 1165 extreme emission-line galaxies (EELGs) at 4<z<9 selected using James Webb Space Telescope (JWST) NIRCam photometry in the Cosmic Evolution Early Release…
A Milky Way-like barred spiral galaxy at a redshift of 3
Luca Costantin, Pablo G. Pérez-González, Yuchen Guo +30
The majority of massive disk galaxies in the local Universe show a stellar barred structure in their central regions, including our Milky Way. Bars are supposed to develop in dynam…
Evolution of the Size-Mass Relation of Star-forming Galaxies Since Revealed by CEERS
Ethan M. Ward, Alexander de la Vega, Bahram Mobasher +19
We combine deep imaging data from the CEERS early release JWST survey and HST imaging from CANDELS to examine the size-mass relation of star-forming galaxies and the morphology-que…
CEERS: 7.7 m PAH Star Formation Rate Calibration with JWST MIRI
