Further analysis allowed the scientists to determine which of the objects are galaxies containing massive central black holes that are actively consuming surrounding material and which are galaxies undergoing rapid bursts of star formation. (sciencedaily.com)
The event will force theorists to explain how flares can unleash energy in such rapid bursts. (sciencemag.org)
Research shows that the warming occurred in two much more rapid bursts. (realclimate.org)
