How do cosmic events contribute to the formation of galactic halos?

Galactic halos are vast regions surrounding galaxies that are composed of dark matter and some older stars. Cosmic events such as the merging of galaxies and interactions with dark matter play a crucial role in the formation of these halos.

Merging of galaxies

When galaxies merge, their gravitational pull interacts with surrounding matter, causing the formation of galactic halos. The merging process can disrupt the structure of the galaxies involved and lead to the redistribution of stars, gas, and dark matter, contributing to the formation of halos.

Interactions with dark matter

Dark matter, which makes up a significant portion of the total mass in the universe, interacts with galaxies and their halos through gravitational forces. The presence of dark matter influences the shape and extent of galactic halos, affecting the overall structure and evolution of galaxies.

Overall, cosmic events such as galaxy merging and interactions with dark matter play a vital role in shaping the evolution of galaxies and the formation of their halos. Understanding these processes is essential in unraveling the mysteries of cosmic evolution and the intricate structure of the universe.
