UNCOVER-z13

UNCOVER-z13 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope during NIRCam imaging for the JWST Ultradeep NIRSpec and NIRCam Observations before the Epoch of Reionization project on November 14, 2023. UNCOVER-z13 is within Abell 2744 supercluster in the constellation Sculptor.

Morphology

UNCOVER-z13 is a Lyman-Break galaxy, and not much more is known about the exact shape of the galaxy.

Discovery

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

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. It is a Lyman-Break galaxy, and was discovered using the same methods as UNCOVER-z13.
