UNCOVER-z13 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope (JWST)[1] during NIRCam imaging for the JWST Ultradeep NIRSpec and NIRCam Observations before the Epoch of Reionization (UNCOVER) project[2] on November 14, 2023. UNCOVER-z13 is within Abell 2744 supercluster in the constellation Sculptor.[3]
UNCOVER-z13 is a Lyman-Break galaxy,[4] and not much more is known about the exact shape of the galaxy.
UNCOVER-z13 was first observed when large amounts of gravitational lensing from Abell 2744 made the galaxy visible. Abell 2744 is around 3.5 billion light-years away from the Milky Way. The gravity of Abell 2744 warps the fabric of space-time sufficiently to magnify the light of more faraway galaxies. The James Webb Space Telescope used the gravitational lensing to discover UNCOVER-z13.
UNCOVER-z12 is a second galaxy which was discovered around the same time. UNCOVER-z12 has a redshift of 12.393, making it the fourth-most distant object ever observed.[5] It is a Lyman-Break galaxy, and was discovered using the same methods as UNCOVER-z13.
