The discovery of the second and third known ultra-compact dwarf galaxies with gargantuan black holes at their cores suggests such a mass mismatch may be common (newscientist.com)
Three projects — the Parkes Pulsar Timing Array in Australia, NANOGrav in North America and the European Pulsar Timing Array in Europe — are monitoring dozens of pulsars for tempo changes that can reveal not only single collisions but the cacophony of gargantuan black holes smashing together throughout the universe.
