Abstract

We report measurements of the galaxy two-point correlation function at cosmic dawn, using photometrically selected sources from the JWST Advanced Deep Extragalactic Survey (JADES). The JWST/NIRCam data set comprises approximately Ng ≃ 7000 photometrically selected Lyman Break Galaxies (LBGs), spanning in the redshift range 5 ≤ z 10, finding a galaxy bias b = 9.6 ± 1.7 for the sample at z = 10.6. The result suggests that the observed sources are hosted by dark matter haloes of approximately Mh ∼ 1010.6 M, in broad agreement with theoretical and numerical modelling of early galaxy formation during the epoch of reionization. Furthermore, the JWST JADES data set enables an unprecedented investi..
