Two teams of astronomers led by researchers at the University of Cambridge have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars — extremely luminous objects powered by supermassive black holes with the mass of a billion suns — regulate the formation of stars and the build - up of the most massive galaxies.

The team also compared the masses of the black holes with the total masses of their host galaxies to determine how much matter they had swallowed.

Simulations of black holes with different masses and spins that match, or which are oddly aligned, require the complex mathematics of Einstein's strong field equations.

LIGO has previously spotted mergers of swirling black holes with masses tens of times that of the sun (SN Online: 9/27/17); the smaller masses of the orbiting duo pointed the finger at neutron stars.

One possibility is that astronomers might be able to detect primordial black holes with an initial mass of 1012 kilograms exploding in the present universe.

Last year, x-ray astronomers also found hints of «intermediate» black holes with hundreds to thousands of times our sun's mass in other galaxies (ScienceNOW, 7 June 2001), but they hadn't measured the gravitational pulls of such holes — the best way to confirm their presence and gauge their masses.
