Physics Galaxy Discussion Questions Solutions -

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.

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. physics galaxy discussion questions solutions

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. Spiral galaxies, like the Milky Way, are characterized

How do galaxy simulations help us understand the role of feedback in regulating star formation? Dark matter also helps to regulate the flow
