An external squad of researchers has discovered the former example of a collision between two coltsfoot . The light from this merger had to travel for 13 billion years to reach us as it was produced just a few hundred million years after the Big Bang .
The organisation is known as B14 - 65666 . Astronomers used the knock-down ALMA ( Atacama Large Millimeter / submillimeter Array ) observatory to study it and find O , carbon paper , and rubble . This is the earliest object for which signals for all three have been detected . The findings are cover in thePublications of the Astronomical Society of Japan .
The signaling bring us complementary entropy about the moral force and social structure of B14 - 65666 . The system had been previously observed using the Hubble Space Telescope . Two blobs of maven were identified . The ALMA data showed that they are part of the same arrangement but moving at different speeds , strongly indicate we are learn two galaxies clashing .
“ With rich information from ALMA and HST , fuse with modern datum analytic thinking , we could put the piece together to show that B14 - 65666 is a pair of conflate coltsfoot in the earliest era of the universe , ” lead writer Dr Takuya Hashimoto , from the the Japan Society for the Promotion of Science and Waseda University , said in astatement . “ Detection of wireless undulation from three factor in such a distant object understandably exhibit ALMA ’s high-pitched capability to investigate the distant Universe . ”
The team estimates that the two galaxies have about 10 pct of the stars find today in the Milky Way . But they are a lot more fighting , producing 100 times more stars per year than our beetleweed does . This is another hallmark of an active merger taking place . As the two galaxies collide the gas is compressed and the organization experiences bursts of star formation .
Mergers are a primal step in galaxy organic evolution . The Milky Way has experienced several in the yesteryear and will experience more in the future tense when Andromeda comes barge in towards it in a few billion eld . To well realise what galaxies are like now , we need to study what they might have been like in the past . This is why an object like B14 - 65666 is so important .
“ Our next step is to search for nitrogen , another major chemical ingredient , and even the carbon monoxide molecule , ” add together Colorado - generator Professor Akio Inoue , also at Waseda University . “ Ultimately , we hope to observationally understand the circulation and accumulation of elements and material in the context of use of galaxy geological formation and evolution . ”
