Introduction
Dark matter is a mysterious substance that makes up a large portion of the universe’s total mass. Its presence can be inferred through its gravitational effects on visible matter, such as galaxies. One of the intriguing aspects of dark matter is the formation and structure of dark matter halos, which are thought to be the gravitational anchors for galaxies. Understanding the properties of these halos is crucial for unraveling the mysteries of dark matter and galactic evolution.
Overview of Dark Matter Halo Collapse
Dark matter halos are thought to form through a hierarchical process, where small clumps of dark matter merge to form larger structures. This process is driven by gravity and is believed to have started shortly after the Big Bang. As the clumps merge and collapse under their own gravitational pull, they form the scaffolding upon which galaxies eventually come into being.
A recent study has shown that if dark matter has self-interactions, the collapse of a halo can result in the formation of a massive enough seed black hole. This finding is significant because it provides a potential mechanism for the origin of supermassive black holes (SMBHs). SMBHs are found at the centers of most galaxies and can have masses millions or even billions of times that of the Sun.
Significance of understanding the origins of supermassive black holes
The formation of SMBHs is still not fully understood. The collapse of pristine gas in protogalaxies is a popular mechanism used to explain the origin of these black holes. However, recent research suggests that self-interacting dark matter can also play a role.
By studying the motion of stars and gas in galaxies, scientists can gather valuable insights into the nature of dark matter. Understanding how dark matter interacts with itself and with visible matter is crucial for determining its properties and the role it plays in the formation and evolution of galaxies.
The discovery that self-interacting dark matter can lead to the formation of massive black holes provides a new avenue for exploring the connection between dark matter and galactic structures. Further research in this area could shed light on the mysterious properties of dark matter and help us unravel the origins of supermassive black holes.
In conclusion, the formation and structure of dark matter halos is an intriguing area of study in cosmology. Recent research suggests that self-interacting dark matter could play a significant role in the formation of supermassive black holes. Understanding the origins of these black holes is crucial for unraveling the mysteries of dark matter and its impact on galactic evolution.

Evolution of the Central Halo
Shrinkage in radius and decrease in rotation due to viscosity
As the collapse process of the central dark matter halo progresses, several changes occur. The halo, which possesses a fixed mass, experiences a reduction in its radius and a slowing down of its rotation. These changes are primarily attributed to the presence of viscosity within the halo. Viscosity, or the internal friction between dark matter particles, acts to dissipate the angular momentum of the halo, resulting in a decrease in its rotational speed.
The eventual collapse of the central halo into a singular state: a seed black hole
Continuing its evolution, the central halo ultimately reaches a point of collapse, transitioning into a singular state known as a seed black hole. This collapse occurs due to the combined effects of shrinking radius and diminishing rotation. The central halo, endowed with angular momentum originating from its rotation, undergoes self-interactions that induce viscosity, leading to the dissipation of the remaining angular momentum. Eventually, this process brings about the formation of a seed black hole.
The seed black hole, in turn, possesses the potential to grow more massive over time by accreting surrounding baryonic matter, such as gas and stars. As it gains mass through the accretion process, the black hole develops into a supermassive black hole, exhibiting immense gravitational pull and influencing the structure and dynamics of its cosmic surroundings.
Research conducted by the University of California – Riverside and funded by various organizations, including the Department of Energy and NASA, highlights the production of seed black holes through the collapse of dark matter halos.

A recent study led by UC Riverside has shed light on the origin of supermassive black holes by investigating the production of seed black holes through the collapse of dark matter halos. The research, conducted by a team of scientists with expertise in both theoretical physics and astrophysics, suggests that the collapse of a dark matter halo can lead to the formation of a seed black hole if dark matter possesses self-interactions.
The study explores the evolution of the central dark matter halo and highlights the key role of viscosity in this process. As the collapse progresses, the halo undergoes a reduction in radius and a slowing down of rotation, primarily due to the presence of internal friction between dark matter particles.
