How Did Supermassive Black Holes Get So Big, So Early? They Might Have Had a Head Start

Supermassive Black Holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large galaxies have one at their centres. However, the JWST has revealed a foundational cosmic mystery. The powerful space telescope, with its ability to observe ancient galaxies in the first billion years after the Big Bang, has shown us …

Early Black Holes Fed 40x Faster than Should Be Possible

The theory goes that black holes accrete material, often from nearby stars. However the theory also suggests there is a limit to how big a black hole can grow due to accretion and certainly shouldn’t be as large as they are seen to be in the early Universe. Black holes it seems, are fighting back …

Chandra X-Ray Observatory finds massive black holes common in early universe

Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.

Steady diet of binary star partners makes black holes grow “supermassive”

A new study by astrophysicists at the University of Utah and the Smithsonian Astrophysical Observatory in Cambridge, Mass., has found a new explanation for the growth of supermassive black holes: they repeatedly capture and swallow single stars from pairs of stars that get too close.

Black Holes, just two numbers is all you need…

Black holes sound wildly complicated. After all, there are all sorts of bizarre things going on: intense gravity, the warping of the fabric of space, the distortion of time itself. But when it comes to describing black holes, it comes down to just two numbers: the mass of the black hole and its spin. That’s right. Everything you physically need to describe a black hole is found in just these two numbers.
