An international team of astronomers led by researchers at the University of California, Riverside, has discovered an unusual massive cluster of young ....
The anatomy of an enigma: a team of astronomers using the Large Binocular Telescope Observatory (LBT) atop Mount Graham in southeastern Arizona collected 17 hours’ worth of light from the abnormally massive elliptical galaxy dubbed C1-23152 (image above). The young galaxy is 12 billion light years away and defies conventional models of its origins as it must have accumulated its enormous mass within 1.8 billion years after the big bang, less than 13% of the present age of the universe. Most elliptical galaxies, such as C1-23152 at the center of a galaxy cluster, take many billions of years to reach their massive sizes. Hence the enduring mystery of how and why these monster objects exist in the early universe. ....
December 18, 2020 A popular theory of galaxy formation suggests that small galaxies merged to form larger ones. But galaxy C1-23152 – 12 billion light-years from Earth – apparently formed itself from gas in the early universe, via exceedingly rapid star formation. C1-23152 rose to a mass of 200 billion suns in just 500 million years. At the height of its star formation, C1-23152 produced roughly 450 stars per year, or more than one per day. The Milky Way, by contrast, produces about two stars per year. Image via INAF/ HST/ NASA/ ESA. An international team of astronomers said on December 10, 2020, that they’ve been able to piece together the growth and rapid evolution of a large galaxy in the early universe. This galaxy, known as C1-23152, existed at a time when the universe was just 1.8 billion years old (in contrast to its current estimated age of about 13.8 billion years). The astronomers acquired 17 hours of observations – coordinated by Paolo Saracco of the ....
