A major puzzle in black hole astronomy is understanding the assembly of \u201csupermassive\u201d black holes\u2014those having masses over a million times that of the Sun. The debate hangs on decades of impressive work but can be summed up simply: Did black holes start massive, grow massive, or build up through mergers? Yiqin Chen from Beijing Normal University and her colleagues have opened up a new way to tackle the problem [2]. They use a long-running experiment called the Parkes Pulsar Timing Array, located in Australia, to probe a possible signal of early-Universe black hole binaries in low-frequency gravitational waves.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have used radio observations of rapidly spinning neutron stars to search for signals from supermassive black hole pairs at the dawn of galaxy formation.
