New Delhi | Jagran News Desk: Astrophysicists on Monday published the largest-ever 3D cosmic map of the Universe after the comprehensive analysis of more than four million galaxies and ultra-bright, energy-packed quasars.

The new results yielded a “complete story of the expansion of the universe”, and are the efforts of hundreds of scientists from around 30 institutions worldwide, said Will Percival of the University of Waterloo in Ontario, Canada.

According to a report by the University of Waterloo, The new results come from the extended Baryon Oscillation Spectroscopic Survey (eBOSS), an international collaboration of more than 100 astrophysicists that is one of the SDSS’s component surveys. The report also states that at the heart of the new results are detailed measurements of more than two million galaxies and quasars covering 11 billion years of cosmic time.

Percival, the director of Waterloo Centre for Astrophysics at the University of Waterloo in a statement said, “Over the last 20 years, the Sloan Digital Sky Survey (SDSS) has created a series of surveys that now span a period of 11 billion years of cosmic history.”

“We have worked to fill in that gap, and we are now using that information to gain a better understanding of this period in our universe,” he added further. The outcome is the representation of the culmination of 15 years of work of Percival.

This map also represents the combined effort of more than 20 years of mapping the universe using the Sloan Foundation telescope.

Dustin Lang, a computational scientist at The Perimeter Institute in the report by University of Waterloo said, “The data released before now have significant legacy value, and have been widely used for many different astrophysical analyses from studies of individual stars through to studies of galaxies and the universe as a whole.” Dustin has also helped in putting together the data.

“It really is incredible that one experiment has produced such a scientific legacy,” the scientist added.
