Theoretical Cosmology: PhD Programs & Math for UK Students

AI Thread Summary
The discussion centers on preparing for PhD applications in theoretical cosmology and galactic evolution. The user, holding a 2:1 Astrophysics Msci from the UK, is considering universities like Durham and exploring options in Europe, while expressing concerns about their qualifications and the competitiveness of their application. They seek advice on how to effectively present their academic interests and experiences in their application. Additionally, the user is looking to strengthen their mathematical skills, feeling their undergraduate program focused more on physics. Recommendations for relevant cosmology literature are provided, emphasizing the importance of identifying potential supervisors and the value of reading foundational texts in the field. The conversation highlights the significance of mentorship in PhD success and suggests that the choice of supervisor may be more critical than the university's reputation.

Hey people.

I hold an Astrophysics Msci (undergraduate masters) at 2:1 in the UK, and I'm currently preparing to apply to PhD programmes in 6-7 months time. I have a few questions. I'm interested in theoretical cosmology, and theories of galactic evolution - I'm looking for good universities in the UK that might be willing to cover a PhD in this area, and so far I have the University of Durham as a candidate (others? possibly considering other places in europe, though it seems foreign phd students have an odd time in most european countries).

I'm weary of the fact that the University of Durham has a very good reputation for physics, but am hoping that the 2:1 I have will be acceptable with the other achievements I have had throughout my degree. I've had an interest in this area ever since i covered a short project on a related topic early on in my degree, and have had an active interest in reading publications in the area, though I may not have understood them all. Is it reasonable to include information like this on an application in such an obvious way?

I would also like to hear people's thoughts on the mathematics that would be needed to tackle an area such as this? since I would very much like to spend what will now be my year off bolstering my math - I feel that my degree spent too much time on physics and not enough on math: I'm a good physicist but fully a lousy mathematician. Any recommendation of books in related math or cosmology areas are welcome.

thank you,

David

Sussex or Leicester might be worth a look. I would look at *people* rather than Universities. There are some good cosmology books by UK people.

Cosmology: A Very Short Introduction (Very Short Introductions) by Peter Coles

The Infinite Cosmos: Questions from the frontiers of cosmology by Joseph Silk

Cosmology: Fourth edition by Michael Rowan-Robinson

An Introduction to Modern Cosmology, 2nd Edition by Andrew Liddle

The Oxford Companion to Cosmology by Andrew Liddle and Jon Loveday [This is a must read! Oxford Companions are usually really good for getting an overview of a field at a reasonable level -- that is, comprehensive but not too advanced...]

I would read these, or Liddle's more advanced works, to get an idea of the mathematics you should be reading & the people you should be seeking out as supervisors

Liddle is at Sussex, where I did my MSc (before he arrived unfortunately!). They have quite a strong theoretical astronomy research tradition. I didn't enjoy the MSc much, but in doing a PhD it's the supervisor that counts...
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
