Scientists have made a groundbreaking breakthrough in understanding the growth of supermassive black holes in the centers of galaxies. By fusing cutting-edge supercomputer simulations with advanced X-ray observations, researchers have reached new heights in deciphering the evolution of these enormous celestial entities.
Employing a hybrid approach that combines modeling of cold gas accretion and black hole mergers, the team has been able to fully reconstruct the growth history of supermassive black holes over 12 billion years of cosmic evolution, starting from the early stages of the Universe. The study revealed that the primary mechanism driving black hole growth was accretion, with mergers also playing a significant role, especially in the last 5 billion years.
Surprisingly, supermassive black holes across all masses expanded much faster in the young Universe, leading to the disappearance of most of them around 7 billion years ago. However, the black hole at the heart of our galaxy, the Milky Way, with a mass equivalent to 4 million times that of the Sun, likely continued to grow and evolve in later cosmic eras.
This research not only sheds light on the growth patterns of black holes but also underscores the dynamic nature of the cosmos, offering invaluable insights into the mysteries of the universe’s evolution.
