A new study has just given a real boost to the old theory of the origin of the Universe: some of the first galaxies are much less massive than they seemed at first
Therefore, finding already enormous galaxies a few hundred million years after the Big Bang was quite a surprise. Data from the James Webb Space Telescope showed early galaxies that appeared to have become so massive quickly that no simulation could explain them. Many began to think that something was going very wrong in our theory of how the Universe was born and evolved, the so-called ‘standard model of Cosmology’.
A new study just published in ‘The Astrophysical Journal’ by a team of researchers led by Katherine Chworowsky, from the University of Texas at Austin, has just given the old theory a real boost: some of those first galaxies are, in fact, much less massive than they seemed at first. principle. And the ‘fault’ that they seemed much larger and heavier to us lies with the central black holes of some of them, which make them appear much larger and brighter than they really are.
