Scientist Found a Long-Standing Galaxy

  • Scientist Found a Long-Standing Galaxy

KYIV (FNI) - Objects that are close to the Milky Way, can be more than 13 billion years, say researchers from the universities of Durham and Harvard. They formed more than a hundred million years after the Big Bang and included some of the first stars that illuminated the cosmos. The results of the study were published in the Astrophysical Journal.

"Professor Frank, Dr. Bose and co-author Dr. Alice Dixson of Durham found that the existing model of galaxy formation explains the data, allowing them to determine the origin of satellite galaxies. The first population of galaxies, perhaps, was formed during the "cosmic dark ages," the cooling period that began after the Big Bang and lasted 100 million years. The second population, which consists of slightly brighter galaxies, seems to have formed hundreds of millions of years after the first," the BBC reports.

"The search for the first galaxies formed in our universe revolving around the Milky Way's own "parade ground" is the astronomical equivalent of discovering the remains of the first humans inhabiting the Earth," said Professor Carlos Frenk of the University of Durham, UK.

The evolutionary model of the galaxy, approved by astronomers, suggests that in the transition between weak galaxies and brighter galaxies, there must be a "break", which is determined by the luminosity function. This should correspond to a halt in a billion years in the formation of galaxies caused by the ionization of hydrogen gas at the end of the dark ages.
