Journal Article
Le Conte, Z. A., Gadotti, D. A., Ferreira, L., Conselice, C. J., de Sá-Freitas, C., Kim, T., …Adams, N. J. (2024). A JWST investigation into the bar fraction at redshifts 1 ≤ z ≤ 3. Monthly Notices of the Royal Astronomical Society, 530(2), 1984-2000. https://doi.org/10.1093/mnras/stae921

The presence of a stellar bar in a disc galaxy indicates that the galaxy hosts in its main part a dynamically settled disc and that bar-driven processes are taking place in shaping its evolution. Studying the cosmic evolution of the bar fraction in d... Read More about A JWST investigation into the bar fraction at redshifts 1 ≤ z ≤ 3.
