What is the relationship between galaxy size and galaxy mass?

How do galaxy simulations help us understand the role of feedback in regulating star formation?

Spiral galaxies, like the Milky Way, are characterized by a central bulge and a disk of stars, gas, and dust, with spiral arms of younger stars and star-forming regions. Elliptical galaxies, on the other hand, are egg-shaped and lack a disk, with a higher proportion of older stars and less gas and dust. physics galaxy discussion questions solutions

Dark matter plays a crucial role in galaxy formation and evolution, as it provides the gravitational scaffolding for normal matter to clump together and form galaxies. Dark matter also helps to regulate the flow of gas and stars within galaxies, influencing the rate of star formation and galaxy growth.

How do galaxy mergers affect the structure and composition of the resulting galaxy? What is the relationship between galaxy size and galaxy mass

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

Galaxy mergers can lead to the formation of a new, more massive galaxy, with a changed structure and composition. The merger can trigger starbursts, and the resulting galaxy may have a different shape, size, and stellar population. Elliptical galaxies, on the other hand, are egg-shaped

There is a well-established relationship between galaxy size and galaxy mass, known as the size-mass relation. This relation shows that more massive galaxies tend to be larger, with a greater radius or diameter.
