She and others recently suggested that a clump of bright, pristine gas in the protogalaxy
CR7 might contain a direct-collapse black hole.
Quasar light absorbed by gas in the protogalaxy has revealed the fingerprints of 25 star-forged elements.
The protogalaxy probably has since coalesced into a giant elliptical galaxy, says David N.
Giovanelli says a small pocket of starlight does not eliminate the cloud as a protogalaxy
Lots of gas and few stars are what astronomerswould expect a protogalaxy to have.
1 is a protogalaxy, it poses theoreticalquestions of galaxy formation.
Smith (University of California, Santa Cruz) suggests that the protogalaxy
was peppered with supergiant gas clouds roughly 3,000 light-years across.
During the formation of disk galaxies, that "other process" is thought to be the spin that the gas acquired while it was still part of a young, puffy protogalaxy
Rather than being a galactic oldster, B2 0902 + 34 may well be a protogalaxy
Felix Mirabel (Center for Nuclear Studies, Saclay, France) and his colleagues have discovered a nebulous region that appears to be another young protogalaxy
