Black holes are remarkable astronomical objects with gravity so strong that nothing, not even light, can escape them. The most gigantic ones, known as “supermassive” black holes, can weigh millions to billions times the mass of the Sun.
So, how do these supermassive black holes become super massive? To answer this question, our teamof astrophysicists looked back in time across the universe’s 13.8 billion-year history to track how supermassive black holes have grown from the early days to today.
We constructed a model of the overall growth history of supermassive black holes spanning the past 12 billion years.
How do supermassive black holes grow?
Supermassive black holes grow primarily in two ways. They can consume gas from their host galaxies in a process called accretion, and they can also merge with each other when two galaxies collide.
