‘Fossils’ of galaxies reveal the formation and evolution of massive galaxies

25 septiembre 2015

Astronomers have observed massive dead galaxies in the universe 4 billion years after the Big Bang. They discovered that the stellar content of these galaxies is strikingly similar to that of massive elliptical galaxies seen locally. Furthermore, they identified progenitors of these dead galaxies when they were forming stars at an earlier cosmic epoch, unveiling the formation and evolution of massive galaxies across 11 billion years of cosmic time.
