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.

Faint galaxies lurking in the dark

Using the most accurate and detailed cosmological simulations available, an international team has made an exciting prediction that may shed new light on our understanding of the universe: a large population of faint galaxies in our cosmic neighbourhood await discovery.

Magnetic heavy stars need company

Astronomers have discovered that magnetic fields in multiple star systems with at least one giant, hot blue star, are much more common than previously thought by scientists. The results significantly improve the understanding of massive stars and their role as progenitors of supernova explosions.

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.

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.

Science Year 2023 – Our Universe

In the course of the Science Year 2023, the AIP will actively participate in various events and formats.

From 20 to 24 March, 150 participants from 25 countries worldwide meet in Potsdam for the IAU Symposium 379 “Dynamical Masses of Local Group Galaxies”. The focus of the conference is on determining the mass of galaxies in our cosmic neighbourhood.
