For many aspects of the simulation, researchers can start their calculations at a fundamental, or ab initio, level with no need for preconceived input data, but processes that are less understood — such as star formation and the growth of supermassive black holes — need to be informed by observation and by making assumptions that can simplify the deluge of calculations.

This enhanced growth of the strength of gravity means that the true energy scale at which the laws of gravity and quantum mechanics clash — and black holes can be made — could be much lower than the traditional expectation.

As such, researchers want to look at as many early supermassive black holes as possible to learn more about their growth and their effects on the rest of the cosmos.

Gathering all this mass in under 690 million years is an enormous challenge for theories of supermassive black hole growth, explains Eduardo Bañados, an astronomer at the Carnegie Institution for Science who led the international team of scientists.

To measure the mass and growth rate of these galaxies» active nuclei — the supermassive black holes at the galaxies» centers — the researchers used data from 12 different ground - based telescopes spread across the globe to complement the data from the Swift satellite.

Simulations show that fractal patterns emerge on the horizons of black holes at mealtime, which could offer insights into their growth.

Meanwhile, a correlation between the rate at which stars form in the central regions of galaxies and the amount of gas that falls into supermassive black holes (mass accretion rate) was known to exist, leading some scientists to suggest that the activity involved in star formation fuels the growth of black holes.

The second will study the formation, growth and ultimate sizes of the supermassive black holes found at the centers of galaxies.

Researchers said the technique could help astronomers address broad questions about galactic evolution, which is intimately tied to the growth and activity of the supermassive black holes that lurk at the heart of most, if not all, galaxies.

These galaxies are known for a much higher rate of star formation compared to sedate Milky Way - like galaxies, making these structures ideal to study galaxy growth and the interplay between gas, dust, stars, and the black holes at the centers of galaxies.

With its unprecedented look at the early Universe in X-rays, the CDF - S gives astronomers the best look yet at the growth of black holes over billions of years starting soon after the Big Bang.

«We are still very uncertain as to the modes of black - hole formation and growth in the early Universe... so we do not have a leading model for this observation to pose problems to,» Chris Willott, an astronomer at the Canadian Astronomy Data Centre in Victoria, reportedly said.
