This is a montage of four small, young galaxies taken from a Hubble Space Telescope Wide Field Camera 3 slitless grism sample of 28 low-mass galaxies located 10 billion light-years away in the Hubble Ultra Deep Field region of the Cosmic Assembly Near-infrared Deep Extragalactic...
Using the slitless grism on Hubble Space Telescope's Wide Field Camera 3 to probe the distant universe, astronomers have found supermassive black holes growing in surprisingly small galaxies. The findings suggest that central black holes formed at an earlier stage in galaxy evolution. This study is part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) and will be published in the Astrophysical Journal.
