Understanding the Birth of Massive Galaxies
Astronomers are on the verge of a groundbreaking discovery regarding the formation of the universe’s colossal elliptical galaxies. For many years, these giant formations, with their football-like shapes, have puzzled scientists, who have struggled to comprehend their origins. New evidence from a study at the University of Southampton suggests that these massive galaxies arose from violent collisions between smaller galaxies billions of years ago.
Researchers conducted an extensive examination of over 100 distant star-forming galaxies using advanced technology from the Atacama Large Millimeter/submillimeter Array, situated in the Chilean highlands. This team, in collaboration with the Purple Mountain Observatory and the Chinese Academy of Science, discovered that such galactic mergers led to significant star formation rates, creating trillions of new stars.
The process, which likely unfolded during the universe’s active evolution phase 8 to 12 billion years ago, involved gas from colliding galaxies collapsing towards their centers. This influx of gas not only spurred massive star creation but also fed burgeoning supermassive black holes.
Incorporating data from cutting-edge instruments like the James Webb Space Telescope and the Euclid satellite, researchers aim to chart a comprehensive picture of early galaxy formation. Understanding these events not only illuminates the past but also sheds light on the cosmic forces shaping our universe’s future. As scientists continue to unveil these galactic mysteries, the quest to understand our universe’s history and evolution is at a thrilling new phase.

How Massive Galaxies Are Formed: A Step-by-Step Process
1. Initial Collision: Smaller galaxies collide, merging their gas and dust.
2. Gas Concentration: The gas from these colliding galaxies collapses towards their centers.
3. Star Formation: This concentration of gas ignites massive star creation, leading to the formation of trillions of stars.
4. Black Hole Growth: The influx of gas also activates the growth of supermassive black holes at the galactic centers.
This process likely unfolded during the universe’s active evolution phase 8 to 12 billion years ago.
