PHY 455: Gravitation and Cosmology.

Course objective : The course will introduce students to special and general relativity, predictions and tests of these theories, and applications, particularly to black holes and cosmology.
Evaluation for this course: Mid-semester exam 30 %, Final exam 40%, and for BS/MS and int.Ph.D students, a project with viva 30%, while for Ph.D students, project and viva 15% and assignments 15%.
TEXTBOOKS AND ONLINE RESOURCES (all textbooks available in Indian editions):
1. Gravity, by J. Hartle
2. Gravitation: Foundations and Frontiers, by T. Padmanabhan
3. A first course in General Relativity, by B Schutz
4. Link to Sean Carroll's lecture notes available here .
5. Link to Eric Poisson's notes on advanced GR here .

OFFICE HOURS: 11: 30 - 12:25 on Wednesdays. Note that we will have several extra contact hours for which attendance will be voluntary. These will be on Saturday mornings and will be for tutorials as well as advice on your project (project discussions will be after mid-term). Tutorials and the venue will be announced in the previous Thursday class.
