The galaxies in the universe are not all established independently, and satellite galaxies and galaxy patterns will be formed around the galaxies, and how such interstellar clusters are formed, and what is the process of structural evolution of galaxy clusters.
The emergence of satellite galaxies
With the evolution of galaxies, some small galaxies will also form around galaxies, or the formation of extra-system galaxies, and the emergence of satellite galaxies is also a natural phenomenon in the evolution of the universe.
After the formation of satellite galaxies, they are usually small galaxies orbiting a larger galaxy, and the emergence of satellite galaxies is also inseparable from the formation and evolution of galaxies.
In the early days of the Big Bang, a large amount of gas and dark matter accumulated, and finally the most primitive galaxies were gradually formed under the gravitational pull of dark matter.
These most primitive galaxies are also under the action of gravity, constantly absorbing the dust and other materials of the surrounding universe, thereby increasing the mass in them, and finally slowly evolving into larger galaxies.
In this process, celestial bodies such as stars and planets are constantly formed, but such a formation process does not exist alone, large galaxies are formed when the gravitational force is large, and small galaxies will also be subject to the gravitational pull of large galaxies, so that they are captured by the gravitational pull of these large galaxies and become satellite galaxies of large galaxies.
The appearance of satellite galaxies is inseparable from the existence of dark matter, and the different distribution of dark matter also leads to different gravitational forces in different places in the universe, and the different gravitational forces also attract other surrounding matter, so that under the gravitational effect of dark matter, smaller galaxies are attracted to the surroundings of large galaxies.
The emergence of satellite galaxies is also related to the tidal forces in the universe, in the process of the evolution of the universe, smaller galaxies are torn apart by the tidal forces, forming galaxy fragments, and these galaxy fragments also have a certain gravitational attraction, and eventually these fragments evolve into satellite galaxies.
The emergence of galaxy clusters
The formation of galaxy clusters can be said to be a very spectacular phenomenon in the universe, which involves many factors and formation processes.
The formation of galaxy clusters is like the spontaneous aggregation of galaxies, and in the early stages after the Big Bang, as a large number of galaxies continue to form, these galaxies interact with each other and come together in a spontaneous way.
In the end, the galaxies that gather together gradually form a relatively stable state, which gives rise to the emergence of galaxy clusters.
In the process of galaxy cluster formation, external forces also have a crucial factor, not only can galaxies spontaneously form clusters, but also the action of external forces can also make multiple galaxies form clusters.
When one galaxy has an impact on another group of galaxies, it will continue to accumulate and attract more galaxies to aggregate, and this mutual attraction force may be tidal force or gravity, and with the intervention of this external force, galaxy clusters will also be formed.
When two galaxies that are too close to each other are close, the galaxies will form a merger, and the merged galaxies will be recombined, and the other galaxies around them will also be affected by the merging galaxies, and even in the process of combining and agglomerating.
After the aggregation and fusion or division of large galaxies, it will cause a series of evolutions, and the surrounding small galaxies attract the fragments of large galaxies to merge, etc., and such processes will form different galaxy clusters.
This process is constantly happening in the universe, and this also provides a steady stream of impetus for the formation of galaxy clusters, splitting and merging to form different galaxy clusters.
With the continuous change of gravity, a relatively stable structure between galaxies is gradually formed, and finally a galaxy cluster in the universe is formed.
Structural evolution of galaxy clusters
There is no essential difference between galaxy clusters and galaxy clusters, only the difference in number and size, and they are also groups of galaxies that are clustered together in a relationship of mutual attraction.
In this process of aggregation, there is almost the same evolutionary process. The main mechanism of formation lies in the effect of gravity, and a large number of galaxies eventually form galaxy groups, and when there are more of them, they form galaxy clusters.
The dynamics of the galaxy cluster is to concentrate the state of the internal galaxies moving with each other and a kind of determination of interaction, the galaxies in the galaxy cluster are affected by various gravitational forces and their internal dynamics, and in the galaxy cluster, the galaxy presents a very complex motion pattern.
There will also be collisions and mergers of galaxies, and even the escape of the rebirth galaxies, etc., all of which have varying degrees of impact on the structure and evolution of galaxy clusters.
Among them, the interaction between galaxies will also promote the evolution of the galaxy, the collision and merger between galaxies will also cause the shape of the galaxy to change, and the merger process of galaxies will also cause the stars in them to evolve, and even new stars will appear.
For the exterior of galaxy clusters, different galaxy clusters also interact with each other, and through gravity, adjacent galaxy clusters will change from each other, and even attract and merge between galaxy clusters.
Such a merger will not only change the structure and dynamics of the galaxy cluster, but also further affect the structural evolution of the galaxy cluster.
There are also a large number of gases in galaxy clusters, and gas also plays an important role in the process of evolution, while receiving changes in temperature, the gas will also undergo processes such as heating, cooling, compression, and release, which will also affect the distribution of gas in the galaxy cluster, thus affecting the evolution of galaxy clusters.
