A telescope in the desert reached back a billion years and revealed something amazing

Here’s what you’ll learn when you read this story:

• About a billion years after the Big Bang, the Universe experienced an era known as the “Epoch of Improvised Atoms” when neutral atoms “when neutral atoms filled the universe with UV stars of single stars.

• Now a new study seeks to understand the conditions of the universe towards the end of the tail of the “cosmic ages” before the reorganization.

• Using ten years of data from the Murchison Widefield Array Telescope located in western Australia, the researchers found that the merger was not “warm,” and therefore hot, about 800 years, about 800 million years after the Big Bang after the Big Bang.

Everyone is familiar with the beginning of our explosion zone – things got really hot again indeed wait until there was a big bang. However, the sequence of these bursts is determined by sound. After the Big Bang, the universe cooled rapidly and expanded until the end – the last 400,000 years – protons and electrons combined to form hydrogen atoms.

As live science notes, what followed is known as the “Cosmic Purk Age” when the universe was filled with this neutral life for billions of billions until the first stars and galaxies arrived. When those ancient stars flashed UV light that stripped their hydrogen atoms of their atoms, the cosmos entered the “The Epoch of Relocation“And the Universe began to resemble what we see today. These are the days of small children, so to speak.

However, unlike a physical parent who records every milestone for their drooling progeny, astrophysicists have no such treasure – instead, they have to go looking for it. For example, we don’t really know what the atmospheric conditions were when the transition from the “dark ages” began. While some theories suggest reunification from a “cold freeze,” a new study from an international team provides evidence the universe was actually warming up before this mass extinction. The results of the study were published internally The Astrophysical Journal.

“As the whole universe evolved, the gas between galaxies expanded and cooled, so we would expect it to be much, much colder,” said Curtin University’s Cathryn Thryn Trott, lead author. “Our measurements show that they are at least being warmed by some amount. Not by much, but it tells us that the cold energy input has been released.”

Spotting something so distant in the past is not easy, and Thott and his team used the Murchison Widefield Array Telescope located in western Australia to facilitate the challenging observation. Operating at 70-300 MHz, the telescope – was purpose-built to find that hydrogen-neutral activity from the “epoch of redirection.” However, the authors needed to do a lot of subtraction to separate what they wanted from the cosmic noise of nearby stars, galaxies, and the Earth’s atmosphere.

Because the team was able to create this filtered data – and get the benefit of ten years it’s worth it – they can make it available by importing. If the universe was cold during this time, it would emit some kind of signal, but the researchers found no evidence of it, suggesting that at least -one The heating was on. The theory is that X-rays from dark nuclear envelopes and stellar debris fueled this heating 800 million years after the Big Bang. They haven’t found a sign of heat for that heat yet, but researchers say it can only happen at that time.

“All of these existing processes will help us find what’s missing,” Rustin University’s Ridhima Nunhokee, co-author of the study, said in a press release. “The signal is definitely getting buried there. It’s just improving on our data, and getting more data, cleaning data, accessing it.”
