LONDON – Poniua’ena, or “invisible rotating source of creation”, is the Hawaiian name of the second furthest quasar ever observed by man. It is located approximately 13.1 billion light years away and contains a huge black hole inside. The discovery, described in an article published in the magazine Astrophysical Journal Letters by experts from the University of Arizona, it was carried out thanks to three Hawaiian observatories: the WM Keck Observatory, the International Gemini Observatory and the United Kingdom Infrared Telescope (UKIRT) owned by the University of Hawaii.”Poniua’ena – he explains Jinyi Yang, of the Steward Observatory of the University of Arizona – it is only the second quasar detected at such a large distance and dating back to the early Universe. The system houses a black hole twice the size of the previous known similar object, “continues the expert, pointing out that quasars are characterized by the highest levels of energy and since astronomers were discovered they wonder about their origins.
“The spectroscopic observations – Yang continues – show that the black hole that feeds PoniuĂ ena has a mass of about 1.5 billion times that of the Sun and was formed about 700 million years after the Big Bang”. The team argues that the size of the black hole poses a challenge for today’s understanding of the Universe, since such a large singularity would take much longer to form.”According to current theory – remember Xiaohui Fan, professor at the Astronomy Department of the University of Arizona – stars and galaxies would have started to form about 400 million years after the Big Bang, as well as the first black holes, but the size of Poniua’ena indicates that the singularities would have taken at least 300 million years more, which means it should have started to form about 100 million years after the Big Bang. “According to the scientists’ statements, therefore, PoniuĂ ena would pose new questions about our understanding of particular phenomena. “This discovery – he comments Joseph Hennawi University of California Santa Barbara and third signature of the article – it’s really exciting. We are really excited to continue the comments and we hope to find answers to the questions that we raised thanks to Poniua’ena “, he concludes.
