Welcome!

The Leibniz Institute for Astrophysics Potsdam (AIP) is dedicated to astrophysical questions ranging from the exploration of our Sun to the evolution of the cosmos. It focuses on the study of cosmic magnetic fields, extragalactic astrophysics and the development of research technologies in the fields of spectroscopy, robotic telescopes and E-science.

Virtual Babelsberg Starry Night

The next lecture of the virtual Babelsberg Starry Nights of the Leibniz Institute for Astrophysics Potsdam (AIP) will be broadcasted starting on Thursday, 15 July 2021 on the YouTube channel "Urknall, Weltall und das Leben". Please note that the lecture will be given in German.

Research Area II: Extragalactic Astrophysics

Galaxies are fundamental cosmic building blocks. At the largest scales, they serve as markers to study the distribution of matter in the universe - active galaxies and quasars are particularly important because of their intrinsic brightness. Nearby objects can be spatially resolved and consist of populations with very different patterns of motion, star formation histories and chemical abundances.

Research Area I: Cosmic Magnetic Fields

Cosmic events are determined by two natural forces: gravity and magnetic fields. The magnetic field research at the AIP is mainly focused on magnetohydrodynamic (MHD) simulations, the magnetically induced activities on the Sun and the stars, solar coronaphysics as well as space weather in our solar system and on planets around other stars.
