Carbonaceous dust grains seen in the first billion years of cosmic time
Large dust reservoirs (up to approximately 10(8 )M(⊙)) have been detected(1–3) in galaxies out to redshift z ≃ 8, when the age of the Universe was only about 600 Myr. Generating substantial amounts of dust within such a short timescale has proven challenging for theories of dust formation(4,5) and h...
