Unexpected information about the galaxy merged after the Big Bang

Previously, scientists believed that starburst clusters formed when galaxies collided about 3 billion years after the Big Bang, but now, two groups of international researchers think this collision occurs. much earlier.

By looking at the ancient past of the universe, the researchers found collisions beginning about 1.5 billion years after the Big Bang, much earlier than originally anticipated.

Research teams led by Iván Oteo of Edinburgh University and Tim Miller of Yale University and Dalhousie University in Nova Scotia used the Atacama Large Millimeter / submillimeter Array telescope (ALMA) and the Atacama Pathfinder Experiment telescope ( APEX) to study the merging of starburst galaxies.

Starburst galaxies create stars at a rapid rate, producing thousands of stars each year. These galaxies stand out later and lie about a billion light-years away from Earth.

Other observations of ALMA and APEX Observatories show that they are two extremely dense groups of galaxies, a group of 14 galaxies and another galaxy made up of ten galaxies. They are the most active star-forming regions, having seen space change drastically from the beginning and galaxies within them are on the verge of collision.

In addition to finding unexpectedly dense groups of galaxies, researchers are also surprised by the rapid growth of starburst galaxies. Both quantum computers and theoretical models predict that it takes more time to develop into giant objects like today.
