Galaxy Merger

The gravitationally bound system that binds all the stars visible is referred to as galaxy. It also consists of various other components such as stellar remnants, interstellar gas, dust, and dark matter. Galaxies are categorized according to their visual morphology as elliptical, spiral and irregular. Many galaxies are thought to have black holes at their active centres, for example; The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. Our main aim at this passage is to understand why different galaxies could merge, interact together or form starburst galaxies, to this day we people have come across the theory of their probability to collide with one another due to their large separation. This process is their basic way to growth, to become bigger leading to heavy expansion. When the two colliding galaxies both have central black holes, they will tend to sink toward the common centre and eventually join together. This pr…
