Astronomers Discover New Kind of Galaxy: Rapidly Star-Forming Galaxies from Early Universe

An artist’s impression of a quasar and neighboring merging galaxy. The galaxies observed by Decarli et al are so distant that no detailed images are possible at present.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have discovered a new kind of galaxy which, although very old — formed less than a billion years after the Big Bang — produces new stars at a rate of more than 100 solar masses per year. An artist’s impression of a quasar and neighboring merging galaxy. The galaxies observed by Decarli et al are so distant that no detailed images are possible at present. This...
