The first year of JWST has revealed a surprisingly large number of luminous galaxy candidates beyond z>10. While some galaxies are already spectroscopically confirmed, there is mounting evidence that a subsample of the candidates with particularly …
We quantify galaxy overdensities around three high-redshift quasars with known [CII] 158 μm companions: PJ231-20 (z = 6.59), PJ308-21 (z = 6.24), and J0305-3150 (z = 6.61). Recent SCUBA2 imaging revealed the presence of 17 submillimeter galaxies …
We report the discovery of a double-peaked Lyman-alpha profile in a galaxy at $z=6.803$, A370p z1, in the parallel Frontier Field of Abell 370. The velocity separation between the blue and red peaks of the Lyman-alpha profile ($\Delta …
We present improved results of the measurement of the correlation between galaxies and the intergalactic medium (IGM) transmission at the end of reionisation. We have gathered a sample of $13$ spectroscopically confirmed Lyman-break galaxies (LBGs) …
