The universe abounds in billions of galaxies distributed in deep space, so why do we see so many of these masses in our universe today? And how did you form and prosper with this form?

In a new study using the Magellan telescope at the Carnegie Las Campanas Observatory in Chile, scientists have been able to answer this mystery.

A research team from the Carnegie Observatory - led by Daniel Kelson - conducted a ten-year survey of tens of thousands of galaxies, and led to these results, which were published in the journal "Manthli Nightsys of the Royal Astronomical Society" on January 15.

A new methodology to solve the mystery
"Scientists adopted a new approach to solve this dilemma, which helped them to describe what was not possible to describe previously," says Kelson in his statement, which was reported by the site "Phys."

The Carnegie-Spitzer-IMACS Redshift Survey was adapted to enable you to study the relationship between the growth of the galaxy and its surrounding environment, over the course of nine billion years ago, the period in which the shape of galaxies now known has become a defined feature. .

On the new methodology followed, study associate researcher Andrew Benson says, "Our method relied on providing new and intuitive insights into how gravity has pushed the universe to gain its current shape, from its very beginning." "This is a direct test based on the observation of one of the pillars of cosmology," he says.

Existing challenges
The first galaxies formed after hundreds of millions of years after the Big Bang, as the universe began to form a hot foggy soup of highly active particles that began to expand outward from the first explosion point, and then cooled and merged into a hydrogen gas bed.

While some of those spots were more dense than others, their attractiveness overcame the expanding path of the universe, causing the substance to collapse inward, forming masses of specific shapes in the universe.

Differences in density resulted in the formation of large or small bodies in locations only. However, mathematical challenges still limit the ability of astronomers to model how the structure of the universe has grown over the past 13 billion years.


The densest blocks Killson explains that "the main goal of our survey is to calculate the mass of stars in a vast array of distant galaxies, and then use this information to craft a new approach to understanding how structure in the universe is formed."

After a large number of observational nights in Las Campanas, scientists were able for the first time to estimate the growth rates of the primary universe masses, which enabled them to conclude that the densest blocks grow faster than the less dense masses.

Then they were able to determine the original distributions of galaxies and growth rates resulting from the change in density, which eventually led to the distribution of galaxies the way they are now.

Therefore, this study was able to provide an easy and accurate description of the reasons and how the intensity changes have grown in the way they are in our universe today, which supports our understanding of the universe in the cradle of its childhood, according to the study authors.

On the results, Carnegie Observatory Director John Mulchae comments, "Many institutions did not have the capacity to implement a project of this size alone. However, the Magellan telescope enabled us to conduct this survey and adopt this new approach that helped us answer this classic question."

"There is no doubt that a project like this requires resources like the one available at the Carnegie Endowment, but it wouldn't have been complete without the vast number of infrared images that we obtained from the Kate Beck and Crowe Tollolo Observatories."
