JWST’s GLIMPSE: A view of the faintest galaxies in the first billion years of cosmic time -- Faint high-redshift galaxies in the early universe constrain the properties of dark matter, the early build-up of stellar mass, and which sources reionized the early universe. The first two years of JWST observations have revealed a wealth of […]
Galaxy-halo connection in cosmology with wide spectroscopic surveys -- Since the early 2000s, wide spectroscopic surveys, in particular multi-fibre experiments, have provided significant insights into the three-dimensional distribution of galaxies and quasars in the Universe, by constraining cosmological parameters through precise measurements of the baryon acoustic oscillation (BAO) scale and the non-linear growth rate of […]
