Eduardo Bañados of Carnegie led a team that found a quasar with the brightest radio show ever seen in the early universe, due to the issuance of a jet of extremely fast material.
The discovery of Bañados was followed by Emmanuel Momjian of the National Observatory of Radioastronomy, which allowed the team to see with unprecedented detail the cast of a quasar that s & # 39; 39; is formed in the first billion years of the existence of the universe. Discoveries, published in two articles in The Astrophysical Journal will allow astronomers to better probe the youth of the universe during an important period of transition to its current state.
Quasars are made up of huge black holes accumulating matter at centers of mbadive galaxies. This newly discovered quasar, called PSO J352.4034-15.3373, is part of a rare breed that not only swallows matter in the black hole but also emits a jet of plasma moving at speeds approaching those of light . This jet makes it extremely brilliant in the frequencies detected by radio telescopes. Although the quasars were identified more than 50 years ago by their high radio broadcasts, we now know that only 10% of them are powerful radio transmitters.
In addition, the light of this quasar has traveled nearly 13 billion 13.7 billion years to reach us here on Earth. P352-15 is the first quasar with obvious evidence of radio jets seen during the first billion years of the history of the universe
"There is a shortage of powerful transmitters Youth radio from the universe and it's the most brilliant radio quasar. "It's the most detailed picture of a galaxy as brilliant at this distance," adds Momjian
The Big Bang started the universe as a hot soup of extremely energetic particles that were developing rapidly.When expanding, it cooled down and merged into neutral hydrogen gas , which left the universe dark, without light sources, up to the gravity of the condensed matter in the first stars and galaxies. About 800 million years after the Big Bang, the l & # 39; energy released by these early galaxies caused the excitation of neutral hydrogen dispersed throughout the universe and the an electron, or ionization, state in which the gas has remained since. 19659005] It is very unusual to find radio-like transmitter quasars like this from the period following the reappearance of the lights of the universe
"The throw of this quasar could serve as a tool for # 39; important calibration to help future projects to penetrate the dark ages and perhaps reveal how the first galaxies have emerged, "concluded Bañados.
