6 de abr. de 2017 · The massive galaxy ZF-COSMOS-20115 was selected from a sample of galaxies 15 identified photometrically as having a spectral break between the H long (1.7 μm) and K s (2.2 μm) bands.
24 de abr. de 2023 · For the first time, a protocluster of seven galaxies has been confirmed at a distance that astronomers refer to as redshift 7.9, or a mere 650 million years after the big bang. Based on the data collected, astronomers calculated the nascent cluster’s future development, finding that it will likely grow in size and mass to resemble the Coma Cluster , a monster of the modern universe.
In June 2015, astronomers reported evidence for Population III stars in the Cosmos Redshift 7 galaxy at z = 6.60. Such stars are likely to have existed in the very early universe (i.e., at high redshift), and may have started the production of chemical elements heavier than hydrogen that are needed for the later formation of planets and life as we know it.
One ideal target is the galaxy COSMOS Redshift 7, known as CR7 for short.Targeting CR7CR7 is one of the oldest, most distant galaxies known, lying at a redshift of z 6.6. Its discovery in 2015 and subsequent observations of bright, ultraviolet-emitting clumps within it have led to broad speculation about the source of its emission.
17 de jun. de 2015 · Galaxy CR7 — short for Cosmos Redshift 7, after the method by which distant objects in the universe are dated — stood out. In an expanding universe, ...
Galaxy Cosmos Redshift 7 is reported to be the brightest of distant galaxies (z > 6) and to contain some of the earliest first stars (first generation; Population III) that produced the chemical elements needed for the later formation of planets and life as we know it. Galaxies by mass and density. Title Galaxy ...
コスモス・レッドシフト7は地球から約130億光年離れた位置にある原始銀河である。 英名のCosmos Redshift 7の頭文字をとってCR7とよばれることが多い 。 史上初めて、これまで確認されていなかった種族IIIの恒星が含まれている銀河である。
