Spectroscopic confirmation of one luminous z=7.96 Lyman break galaxy in a 4.8 arcmin² COSMOS field implies a surface density of 0.21 arcmin⁻², about 10 times higher than wide-area surveys and hinting at a z~8 overdensity.

Validating z > 7.5 Lyman Break Galaxy candidates in the COSMOS field with JWST/PASSAGE
Spectroscopic confirmation of one luminous z=7.96 Lyman break galaxy in a 4.8 arcmin² COSMOS field implies a surface density of 0.21 arcmin⁻², about 10 times higher than wide-area surveys and hinting at a z~8 overdensity.
