Astronomers using NASA's Chandra X-ray Observatory have discovered a distant quasar with a black hole growing faster than the Eddington limit, shedding light on how supermassive black holes formed early in the universe. The black hole, about a billion times the Sun's mass, is accreting material at a rate 2.4 times the typical maximum, which may explain the rapid emergence of massive black holes shortly after the Big Bang.
A study of a distant galaxy suggests supermassive black holes may be smaller than previously thought, challenging existing models of cosmic growth. The black hole at the core of a galaxy over 12 billion light years away is estimated to be about one billion suns, much less than earlier assumptions, due to intense radiation blowing gas away and limiting its growth.
Contrary to the theory of relativity, research from the University of Michigan has found that large cosmic structures, such as galaxy clusters, are expanding at a slower rate than expected. These structures, which form the cosmic web of galaxies, assemble in groups rather than being randomly distributed, starting as small aggregates of matter that later develop into individual galaxies, clusters, and filaments.
