Scientists use Alma telescope to re shoot Harbert ultra deep space (video)-www.sdcp.cn

The scientists used the ALMA telescope to pat Harbert ultra deep space Harbert Space Telescope astronomers shot with deep field 3D according to recent observations, astronomers can be made from 2 million years after the big bang to the present gas generating three-dimensional space star map Tencent news according to foreign media reports, the famous photo of Harbert ultra deep field (HUDF) for us to expose a mysterious deep space angle. Recently, a team composed of multinational astronomers with Atta Kama large millimeter wave array (ALMA) to observe the same area. In the millimeter wave band, the new observations are much longer than ever before, and the imaging is sharper. For a large amount of gas in different positions, we could not observe them in the past, and now we can trace them. This allows us to produce new insights on the gold period of the formation of galaxies in the universe 10 billion years ago. The researchers presented their findings today at an academic conference in California. The results are also published in several journals. Like the pioneering deep space observations of the Harbert telescope, scientists have used ALMA to make a "blind" search of a particular region of the universe to see what happens. The National Radio Astronomy Observatory astronomer Chris Carilli said that they have completed the first blind search for 3D low temperature gas in the early universe, found a lot before the deep space has not been seen in the detection of galaxies. Unlike Harbert’s observation of bright objects in the visible and infrared wavelengths. The ALMA observation is the millimeter wave radiation released by the low temperature gas and dust. These low temperature gas and dust are the raw materials of star formation. The ability of the ALMA to enable astronomers to study some of the past difficult to observe objects, such as the mass of the nebula and the original disk, as well as some of the visible light in the dark. The latest ALMA observations are devoted to carbon rich galaxies. The presence of carbon monoxide means that there is a large amount of gas enrichment in the region, which is conducive to the formation of new stars. These gases are the key to the birth of the galaxy, but the Harbert telescope is unable to observe them. For a long time, the formation and evolution of galaxies in the gaps of the puzzle, now ALMA will finally make up it. Ma Putian the astronomer Roberto Decarli said that these newly discovered Co rich galaxy may make great contribution to the formation of stars in the universe. ALMA gave us a way to study the early formation and organization of the universe. New observations of HUDF using ALMA include two distinct but complementary data: continuous observations reveal the release of dust and the formation of stars. Linear survey of the attention is the low temperature gas molecules is how to help the formation of stars. The latter data are particularly valuable because it contains information about redshift. Red shift is caused by the expansion of the universe, the greater the red shift means that the farther away from us, the longer the time. According to recent observations, astronomers have been able to create a three-dimensional gas generation map from 2 million years after the big bang.
