New Model Explains Growth of Black Holes

In what could be termed as a new milestone, an international team of astronomers has shed light on how black holes grow over time by developing a new model to predict if growth by accretion or by mergers is dominant.

The New Model

• The team developed a theoretical model to determine the main channel for the growth of black holes. The model is valid from the present day to about 13 billion years ago. The scientists believe that the first black holes started to form approximately with the first population of stars, over 13.5 billion years ago.
• The astronomers tested their ....
