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.

Betelgeuse recovers – for now

New observations of the red supergiant suggest that the 2019 mass ejection of its atmosphere might significantly affects its fate. This doesn't mean Betelgeuse is going to explode any time soon, but the late-life convulsions yield clues as to how red stars lose mass late in their lives as their nuclear fusion furnaces burn out, before exploding as supernovae.

Carl Zeiss Foundation research group grant for Dr Tobias Buck

Tobias Buck will start a junior research group at Heidelberg University dedicated to the topic of machine learning in astrophysics. The research project is funded by the Carl Zeiss Foundation with about 1.5 million euros over six years.

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.

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.

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.
