CEERS2-588 is a Lyman-break galaxy discovered in 2022 by the Cosmic Evolution Early Release Science (CEERS) project team using the James Webb Space Telescope. It is located in the COSMOS region of the sky, an ultra-deep field that has been extensively studied by a variety of telescopes.

CEERS2-588 is a Lyman-break galaxy, only 3,000 light-years across, about 100 times smaller than our Milky Way. Despite its small size, CEERS2-588 hosts a supermassive black hole with a mass 50 million times that of our Sun. The ratio of the black hole mass to the galaxy mass in CEERS2-588 is the highest ever observed.
CEERS2-588 was identified in the Cosmic Evolution Early Release Science (CEERS) survey data, which was designed to observe the z > 10 universe. The initial observations were part of the first public data release on July 14, 2022. The galaxy was initially identified through photometric analysis and later confirmed spectroscopically by NIRSpec. The CEERS team found several bright candidates, including CEERS2-588, during the initial months of JWST's operation.
Observations
[edit]Scientists on February 29, 2024, proposed to reobserve the galaxy CEERS2-588, the brightest ever seen at a redshift greater than 11, with the James Webb Space Telescope. They will do so using the MIRI MRS instrument to search for strong optical emission lines. If they find them, they can better understand the stellar mass, star formation rate, metallicity, active galactic nucleus (AGN) activity, and burst formation of this galaxy. This will help us better understand early galaxies. If they do not find emission lines, however, they will have to wonder how a galaxy so bright in the ultraviolet can have such faint emission lines. Astronomers will study CEERS2-588 with the MIRI MRS instrument and F560W images to better understand this galaxy.
