Galaxy growth in a massive halo in the first billion years of cosmic history
Bayliss, M. B.; Béthermin, M.; Murphy, E. J. +34 more
According to the current understanding of cosmic structure formation, the precursors of the most massive structures in the Universe began to form shortly after the Big Bang, in regions corresponding to the largest fluctuations in the cosmic density field. Observing these structures during their period of active growth and assembly—the first few hu…
A massive core for a cluster of galaxies at a redshift of 4.3
Béthermin, M.; Murphy, E. J.; Greve, T. R. +35 more
Massive galaxy clusters have been found that date to times as early as three billion years after the Big Bang, containing stars that formed at even earlier epochs1-3. The high-redshift progenitors of these galaxy clusters—termed `protoclusters'—can be identified in cosmological simulations that have the highest overdensities (greater-th…
The gravitationally unstable gas disk of a starburst galaxy 12 billion years ago
Yun, M. S.; Iono, D.; Kohno, K. +18 more
Galaxies in the early Universe that are bright at submillimetre wavelengths (submillimetre-bright galaxies) are forming stars at a rate roughly 1,000 times higher than the Milky Way. A large fraction of the new stars form in the central kiloparsec of the galaxy1-3, a region that is comparable in size to the massive, quiescent galaxies f…
