Scientists Working to Decode Signal From Earliest Years of Universe

Mysterious like the big explosion that gave birth to the universe is the short, but the bustling that followed it immediately. How did the universe from a unified sea turned from darkness to a chaotic vortex filled with radioactive stars? How were these stars the first, and how they were born?

So far, we have very strong doubts, but there are no difficult answers. One of the reasons is that the light from this period, called the cosmic dawn, is very weak, which makes almost impossible to deduce the features of these first cosmic things, not to mention their monitoring directly.

But this is about to change, according to a team of international astronomers. In a new study published in the magazine Nature astronomyAstronomers argue that we are about to decipher the radio signal, which has been emitted only by one hundred million of the big explosion. Known as a 21 cm signal, which indicates the outstanding wavelength, this explosion was launched from radiation as the distance of the universe on the stock exchange was born the first stars and black holes.

“This is a unique opportunity to learn how the first light of the universe appeared in the dark,” said Anastasia Valcov, an astronomer of the University of Cambridge, in a statement on the work. “Moving from a cold and dark world to one full of stars is a story that we only started to understand.”

After several hundreds of thousands of years of cooling after the big explosion, the first atoms in the universe were greatly neutral atoms made of positively charged and negatively charged proton.

But the formation of the first stars is unbalanced. When these cosmic reactors came online, they radiate the active light enough to restore this predominance of neutral hydrogen atoms. In this process, they emitted from the photons that produced light in the wavelength of 21 centimeters, making it an unambiguous sign when the first cosmic structures formed. The decoding of these emissions will be tantamount to obtaining a skeleton key to the dawn of the universe.

And Roll Roll, please: Employment of the radio experiment for the analysis of the cosmic hydrogen telescope, which is currently undergoing calibration, and a massive square kilometer group, which is under construction Australia, researchers say they have developed a model that can bother the fans of the first stars, and sometimes the third population stars, which are locked within 21 cm.

While developing the model, their main revelation was that so far, astronomers properly represent the effect of stars systems called X -ray diodes between these first stars. These are the systems in which a black hole or the neutron star stripped materials from a more normal star revolving around, and produces light in the X -ray spectrum. In short, the X -ray diodes seem to be brighter and more numerous than previously thought.

“We are the first group that is constantly designed to adopt a 21 degree signal for the first stars, including the effect of ultraviolet star light and X -ray emissions from the X -ray produced diodes when the first stars die.” “These ideas are derived from simulations that integrate the primitive conditions of the universe, such as the composition of hydrogen Helium caused by the big explosion.”

Finally, it is another promising leap forward in the field of radio astronomy, as recent developments began to detect the world of “low -roof” brightness – a potential depth as well, with a promise to shed light on our understanding of the cosmic dawn has never been.

“The predictions that we are reporting to have great effects on our understanding of the first stars in the universe. “We show evidence that our radio telescopes can tell us details about the mass of these first stars and how perhaps these early lights are completely different from today’s stars.”
