(ORDO NEWS) — In most cases, supermassive black holes are located in the central part of the galaxy, but the latest research by specialists has shown that some may well move around the entire “galactic home”. This is reported by Science Alert.
Such black holes are called “wanderers”. Their feature is that it is almost impossible to monitor such objects. Using a completely new set of simulations, scientists were able to roughly determine exactly how many wandering black holes are present in the universe and where exactly they are located.
Experts believe that in this way they will be able to understand where these huge objects came from, the mass of which is almost billions more than the mass of the Sun.
The process of their emergence and further growth remains a mystery to this day.
Cosmologists suggest that every galaxy has a supermassive black hole at its center. If we talk about the emergence of small objects that have stellar mass, then they appear as a result of the collapse of the core of massive stars.
The main theory behind the growth of supermassive black holes is that they absorb huge amounts of gas, dust, other black holes and stars.
The absorption of another black hole occurs when galaxies collide with each other. The process is long enough and it can be prevented at any time. This leads to the emergence of “wanderers”.
Angelo Ricarte and his colleagues used a special cosmological model of Romulus in order to roughly establish how often such collisions occurred in the past and how many “wanderers” were formed as a result.
They managed to find out that 12 supermassive wandering black holes may be present in the Milky Way, which are located far from the center of the galaxy.
