Masters Level Lectures & Exercises WS 2012/13

Thursday 14:15-16:00 Lectures, 16:00-17:00 Exercises

Lecturers: Simon Glover (glover@uni-heidelberg.de) and Hans-Walter Rix (rix@mpia.de) 

Tutor: Laszlo Szucs szucsl@uni-heidelberg.de

Location: Philosophenweg 12, nHS, Seminarraum

Scope

  • Homogeneous and isotropic cosmology (4): Friedmann-Lemaître models, geometry, redshift and dynamics; parameters, distance measures and ages; thermal evolution, freezing out of reactions; primordial nucleo-synthesis and recombination
  • Inhomogeneities in the universe (5): Evolution of density and velocity perturbations; power spectra, Zel’dovich approximation and nonlinear evolution; spherical collapse model and extended Press-Schechter formalism
  • Early universe (3): Structures in the Cosmic Microwave Background, simplified theory, power spectrum and interpretation; basics of cosmic inflation; accelerated expansion, dark energy and possible cosmological effects
  • Late universe (3): Structures in the evolved universe; large scale gas and galaxy distribution, power spectrum and interpretation; gravitational lenses, cosmic shearing and amplification; evolution of the galaxy cluster population

Objective

Detailed presentation of the cosmological standard model, the cosmological evolution and structure formation for students with special interest in astronomy and astrophysics, in particle astrophysics and in theoretical physics

Grades and credit points on the basis of homework assignments and final in-class exam.
