Studying astrophysics in graduate school

[RedQueen]

Hello again,

After a recent course in extragalactic astronomy, I have realized the field of astrophysics is quite beautiful. I am incredibly fascinated in the cosmological aspect of astrophysics along with high-energy aspects as well: AGN, Neutron stars, Black Holes. How competitive is studying cosmology and astrophysics in grad school compared to high-energy physics, for example? Also, how much does high-energy physics intermingle with cosmology and astrophysics especially in the theoretical sense?

Studying cosmology and astrophysics in grad school is generally quite competitive, especially in the theoretical sense. There are many different sub-disciplines within the field, and those interested in pursuing a career in the field will need to demonstrate their knowledge in the various aspects. High-energy physics, in particular, is an incredibly interrelated field with cosmology and astrophysics. Many of the same fundamental principles apply to both fields, such as quantum mechanics and general relativity. In addition, many of the same techniques are used to study phenomena in both fields, such as numerical simulations and observational techniques. As a result, it is common for researchers in the two fields to collaborate on projects.
