The proposal of an international research group led byINAF (National Institute of Astrophysics) is going to build a new one telescope hunting for old gamma-ray bursts which originated from explosions of the first stars of the universe. The proposal was published on Natural Astronomy.
the telescope HUGO (High-redshift Universe GRB Observatory) will have a diameter of approximately 3-4 meters and will Vera Rubin Observatory (Vro) under construction in Chile, which is 8.4 meters in diameter and will work with visible radiation. Their combined observations allow the two telescopes to near and weak lightning of those issued more than 12 billion years ago. The two will perceive the same things at the same time.
THE gamma bursts (GRB) are explosions that release rays of matter at speeds close to light. These are extremely energetic and highly luminous events in the frequencies of gamma rays to cover all other high energy sources in the universe.
Those that last a few seconds or longer are associated with massive stellar outbursts 10 times higher than that of the sun. After the initial explosion, the star enters a phase of decay for a few days, obscuring the galaxy up to 100 times.
In contrast, the sources Hugo revealed that Vro didn’t see would most likely be very old lightning. We estimated that we could observe about 10 Grb that occurred more than 12.8 billion years ago and even some that were ejected as far as 13.2 billion years ago, so about 500 million years after the Big Bang.
