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.

We are colourful: The AIP participates in Pride Day 2022

At the Leibniz Institute for Astrophysics Potsdam (AIP), people not only of different nationalities but also of different sexual orientations or identities work closely together. On Pride Day Germany 2022, the AIP visibly shows to the outside world how a respectful and tolerant working atmosphere is lived at the Babelsberg campus.

Astronomical treasure chest: Digitization project for photographic plates completed

The fourth and final data release of the APPLAUSE project offers a total of 94,000 digitized astronomical photographic plates, which were analysed and catalogued using modern methods like machine learning. In addition to scans of plates from Bamberg and the Karl Schwarzschild Observatory near Jena, digitized images from the Vatican Observatory now become available for the first time.

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.

The puzzling link between star formation and radio emission in galaxies

On the 50th anniversary of the discovery of a close connection between star formation in galaxies and their infrared and radio radiation, researchers at the Leibniz Institute for Astrophysics Potsdam (AIP) have now deciphered the underlying physics. To this end, they used novel computer simulations of galaxy formation with a complete modelling of cosmic rays.

AIP Thinkshop 2022
07.09.2022 – 09.09.2022
Scientific

The AIP aims to bring together the astrophysics community to discuss exoplanet atmospheres in high spectral resolution in its Thinkshop series. We therefore invite scientists to come to Potsdam to discuss the latest techniques for observations, their analysis, and the next-generation instruments in September 2022. The AIP is a member of the ELT-ANDES consortium.
