This path is recommended for those particularly interested in theoretical and numerical modeling of astrophysical sources or basic physical processes. The main topics for a potential thesis in this field include plasma physics (especially in the solar corona, solar wind and Earth's magnetosphere, from the fluid to the kinetic level), relativistic or high-energy astrophysics (the study of compact objects like neutron stars and black holes, multi-messenger astrophysics including gravitational waves, particle acceleration mechanisms and non-thermal radiative processes), and aspects of cosmology, particularly the evolution of the first stars and first galaxies, and stellar archaeology.

The Theoretical Astrophysics path naturally fits within the Astrophysics curriculum, whose general rules must be followed when preparing this study plan. Below are some recommendations for choosing core, related/integrative, and elective astrophysical courses for this path.
