SUMMARY

The discussion centers on the distinction between protogalactic clouds and protogalaxies in the context of galaxy formation. Protogalactic clouds are formed from fluctuations in density that trap gas and dust, leading to the creation of protogalactic galaxies, which subsequently develop into galactic disks. In contrast, protogalaxies arise from the clumping of dark matter and regular matter, which combine to form galaxies. The consensus indicates that dark matter plays a crucial role in the formation of large-scale cosmological structures.

PREREQUISITES
  • Understanding of protogalactic clouds and their role in galaxy formation
  • Knowledge of dark matter and its influence on cosmic structures
  • Familiarity with the concept of galactic disks
  • Basic grasp of kinematics in astrophysics
NEXT STEPS
  • Research the role of dark matter in galaxy formation
  • Study the process of galactic disk formation from protogalactic clouds
  • Explore the differences between protogalaxies and protogalactic clouds
  • Investigate kinematic models used in cosmology
USEFUL FOR

Astronomers, astrophysicists, and students studying galaxy formation and cosmology will benefit from this discussion.

I'm researching the creation of galaxies and I've came across these two terms. In my research on theory says that the fluctuations in density of space trapped gas and dust, which formed protogalactic galaxies that then forms a galactic disk. The other one says that the clumping of dark matter and regular matter created protogaxies that then combine to form a galaxy. Which theory is more accurate and what is the difference between these two terms.
Thanks!

I am not an expert on this subject, but I understand that dark matter is responsible for galactic formation (your second scenario).
 
Kinemetrics are complicated. Dark matter is generally viewed as indispensable in the formation of large [cosmological] scale structures.
