What are the implications of galaxy surveys for our understanding of galaxy evolution?

Galaxy surveys have revealed a wealth of information about galaxy properties, distributions, and evolution. For example, surveys have shown that galaxies evolve along a tight correlation between galaxy mass and star formation rate, known as the star-forming main sequence. What is the relationship between galaxy size and galaxy mass

AGN can influence galaxy growth and evolution by regulating the flow of gas and stars, triggering starbursts, and shaping the galaxy's structure and composition.

What is the role of dark matter in galaxy formation and evolution? What are the implications of galaxy surveys for

Before diving into discussion questions and solutions, it's essential to grasp the fundamental concepts of galaxy physics. A galaxy is a massive, gravitationally bound system consisting of stars, stellar remnants, interstellar gas, dust, and dark matter. Galaxies come in various shapes and sizes, with our own Milky Way being a barred spiral galaxy.
