Star Formation in Giant Molecular Clouds
Stars form in dense clumps within giant molecular clouds. The authors of this paper find a strong relationship between the gravitational growth of these clumps, and the rate of formation of stars within the clumps.
Simulating Massive Black Hole Seed Formation
What is the connection between galaxy mass and supermassive black hole occupation?
Assessing the Standard Cosmological Model
The standard model of cosmology is simple, elegant, and very successful. How do we tell that whether our model is doing well? And what phenomena does it still have trouble explaining?
