Gravity+ track #
Looking to specialize in gravity in your Master’s programme?
The Gravity+ synergy track reflects the unique Radboud University expertise on the role of gravity in the universe, from the largest to the smallest length scales. Follow this track during your Master’s programme in Mathematics or Particle & Astrophysics. We aim to bring students to the forefront of international research in gravity.

- For the Gravity+ track as part of Mathematics you should follow at least 12EC of these courses as well as 24EC of mathematical physics electives. Always check the current Mathematics Education and Examination Regulations (OER) for the precise requirements!
Courses #
General Relativity (NWI-NM107B, 9EC) Conveying the fundamental geometric concepts of the theory of general relativity and the techniques required to express them quantitatively. (Core course for the Physics & Astronomy Gravity+ track)
Gravity+ club (NWI-NM124, 3EC) A seminar-style course with annually changing overall theme, providing the opportunity to engage with local staff and contempory gravity research. (Core course for the Physics & Astronomy Gravity+ track)
Foundations of Gravitational Waves & Black Hole Perturbation Theory (NWI-NM125, 3EC) This courses studies gravitational waves in full non-linear general relativity and perturbation theory in black hole spacetimes, connecting to recent developments in gravitational wave research and black hole physics.
Quantum Gravity (NWI-NM114, 6EC) An introductory course covering different ways of quantising gravity, perturbative and nonperturbative, covariant and canonical.
Quantum Geometry (NWI-NM110, 6EC) This courses discusses the gravitational path integral in a lower-dimensional setting, leading up to a random surface description of two-dimensional quantum gravity coupled to conformal field theories.
Quantum Field Theory (NWI-NM040B, 6EC) Introducing the corner stone of high energy physics, this course introduces the modern concepts of quantum field theory of interactions between fundamental particles, with special attention to explicit calculation of physical observables.
Foundations and Frontiers of Gravitational Wave Astrophysics (NWI-NM024C, 6EC) This course gives an overview of the formation of compact binary systems and the way gravitational wave detectors are used to study these astrophysical sources.
Gravitational Wave Astrophysics: Statistics and Data Analysis (NWI-NM130, 3EC) In this course you will learn about the statistics and data analysis required to analyze gravitational wave data.
Black Holes and Accretion (NWI-NM018B, 6EC) In this course you learn about the accretion of gas onto black holes and associated astrophysical phenomena.
Singularities and Black Holes (NWI-WM159B, 8EC) This course covers mathematical aspects of Lorentzian geometry, from causality theory and global hyperbolicity to the singularity theorems of Penrose and Hawking.
Nonlinear Wave Equations (NWI-WM153B, 8EC) This course covers the mathematics of nonlinear second-order partial differential equations and their solutions. In the context of Einstein’s equations, they play a fundamental role in determining the dynamical and geometric properties of space and time.
Riemannian Geometry (NWI-WM310, 8EC) This introductory course covers the basics of Riemannian geometry, including intrinsic and extrinsic notions of curvature and their interplay. The indefinite variation of Lorentzian geometry is the mathematical language needed to understand Einstein’s general theory of relativity.
