Six ancient barred spiral galaxies identified by the James Webb Space Telescope
An article accepted for publication in “The Astrophysical Journal Letters” reports the discovery of six barred spiral galaxies that are between 8.4 and 11 billion years old. A team of researchers used the James Webb Space Telescope within the CEERS survey to observe enough details of these galaxies to identify the two extensions of stars that start from their center and reach the outer disk in a structure that resembles a bar. It’s a crucial structure for the evolution of these galaxies, as it favors the growth of the supermassive black holes at their center and star formation in their central regions.
