The school is organized by the International Astronomical Union (IAU), the Norwegian Academy of Science and Letters (NASL) and by the South African Astronomical Observatory (SAAO). This school will take place over a three-week period and is aimed towards early graduate students (MSc/PhD) in Physics, Astronomy or Astrophysics from African countries, although we will also consider final year BSc students with a strong intention of entering a graduate program on Astronomy and Astrophysics. The lecturers are invited experts from around the world.
