The Max Planck Institute for Gravitational Physics (Albert Einstein Institute) is a Max Planck Institute whose research is aimed at investigating Einstein's theory of relativity and beyond: Mathematics, quantum gravity, astrophysical relativity, and gravitational wave astronomy. The Institute was founded in 1995 and is located in Golm, Potsdam and in Hannover. The Potsdam-Golm institute is organized in three research divisions and four independent research groups, while the Hannover institute has two divisions and three independent research groups.
The institute is involved in a number of collaborations and projects: it is a main partner in the gravitational wave detector GEO 600; institute scientists are involved in analyzing data for the detectors of the LIGO Scientific Collaboration and in planning and preparing the space-based detector LISA. The institute is also a major player in the Einstein@Home and PyCBC projects.
From 1998 to 2015[1], the institute has published the open access review journal Living Reviews in Relativity.
History
The newly founded institute started its work in April 1995 and has been located in Potsdam-Golm since 1999[2].
In 2002 the Institute opened a branch at the Universität Hannover with a focus on data analysis and the development and operation of gravitational-wave detectors on Earth and in space. The Hannover institute originated from the Institute for Atom and Molecule Physics (AMP) of the Universität Hannover, which was established in 1979 by the Department of Physics.
Research
The research focus of the institute is in the field of general relativity. It covers theoretical and experimental gravitational physics, quantum gravity, multi-messenger astronomy and cosmology. The institute has a strong research focus on gravitational-wave astronomy: four out of five departments are working on different aspects of this research field. Central research topics are:
- source modeling (binary neutron stars, binary black holes, mixed binaries, stellar core collapse)
- experimental work on gravitational-wave detectors – both on Earth and in space
- solving the two-body problem in general relativity
- analytical and numerical solutions of Einstein's equations
- development and implementation of data analysis algorithms for gravitational-wave searches
- follow-up analyses to infer properties of the gravitational-wave sources
All these efforts enable a new kind of astronomy, which began with the first direct detection of gravitational waves on Earth.
Scientists of the institute also work towards the unification of the fundamental theories of physics – general relativity and quantum mechanics – into a theory of quantum gravity.
Departments
- Alessandra Buonanno’s Astrophysical and Cosmological Relativity department[3] at AEI Potsdam develops analytical and numerical models of gravitational-wave sources. They are used for data analysis, parameter estimation, and for tests of Einstein’s theory of general relativity.
- Masaru Shibata’s Computational Relativistic Astrophysics department[4] at AEI Potsdam studies mergers of black holes or neutron stars and the collapse of stellar cores. The department also works on more fundamental aspects of general relativity with numerical tools.
- The Quantum Gravity and Unified Theories department[5] (acting director since August 2020: Alessandra Buonanno) at AEI Potsdam works on the development of a quantum theory of gravity, based on conformal field theory, string theory, and supergravity and symmetries.
- The research focus of Karsten Danzmann’s department Laser Interferometry and Gravitational Wave Astronomy[6] at AEI Hannover is on the development and operation of gravitational-wave detectors on Earth and in space. This includes laboratory experiments in quantum optics and laser physics.
- Bruce Allen’s department Observational Relativity and Cosmology[7] at AEI Hannover studies observational consequences of general relativity, including the search for and analysis of gravitational-wave signals in data from ground-based detectors, and the operation of the Einstein@Home project. The department also works on searches for gamma-ray and radio pulsars, and on theoretical aspects of black holes.

Independent research groups
Permanent independent research groups
- Geometry and Gravitation[8] (led by Lars Andersson) at AEI Potsdam. This research group studies fundamental questions in the theory of gravity and related physical theories with mathematical methods.
- Searching for Continuous Gravitational Waves[9] (led by Maria Alessandra Papa) at AEI Hannover. This research group works on searches for as of today undetected continuous gravitational waves, which are expected from rapidly rotating neutron stars.
Independent research groups
- Binary Merger Observations and Numerical Relativity[10] (led by Frank Ohme) at AEI Hannover. The independent research group works on gravitational-wave data analysis and predictions of wave forms for signals from merging black holes and neutron stars. The studies are based on numerical simulations of these processes.
- Exceptional Quantum Gravity (Emeritus group, led by Hermann Nicolai) at AEI Potsdam. This research group is funded by an ERC Advanced Grant. Its research is concerned with a symmetry-based approach to a consistent theory of quantum gravity.
- Gravitational Theory and Cosmology[11] (led by Anna Ijjas) at AEI Hannover. This Lise Meitner Research Group[12] uses mathematical and numerical relativity to study cosmological theories and their relationship to black hole physics.
- Gravity, Quantum Fields and Information[13] (led by Michal P. Heller) at AEI Potsdam. This independent research group, funded by the Alexander von Humboldt Foundation through a Sofia Kovalevskaya Award, works on the intersection of gravitational and high-energy physics using quantum information science.
- Historical Epistemology of the Final Theory Program[14] (led by Alexander Blum) at AEI Potsdam. This research group focuses on the history of the search for a quantum gravity theory. The group is a joint Max Planck Research Group of the Max Planck Institute for the History of Science in Berlin and the Max Planck Institute for Gravitational Physics in Potsdam.
- Theoretical Cosmology[15] (led by Jean-Luc Lehners) at AEI Potsdam. This funded research group is funded by an ERC Consolidator Grant and works on theoretical physics of the very early universe and the Big Bang.
Graduate Program
The institute participates in two International Max Planck Research Schools (IMPRS). Such research schools are graduate programs run by Max Planck Institutes in partnership with local universities, offering a Ph.D. degree. The IMPRS for Mathematical and Physical Aspects of Gravitation, Cosmology and Quantum Field Theory partners with the Institute for Mathematics at University of Potsdam, the Institute of Physics at Humboldt University, IIT Bombay, Chennai Mathematical Institute, and the Institute of Theoretical Physics of the Chinese Academy of Sciences[16]
The IMPRS on Gravitational Wave Astronomy is run in two collaborating branches, one in Hannover and one in Potsdam-Golm. The Hannover branch cooperates with the Leibniz University Hannover and the Laser Zentrum Hannover e.V.[17]. The Potsdam branch partners with the Humboldt University, the University of Potsdam and the Leibniz Institute for Astrophysics. It cooperates with the IMPRS for Mathematical and Physical Aspects of Gravitation, Cosmology and Quantum Field Theory (also at AEI Potsdam), the Master’s degree program in astrophysics at the University of Potsdam, the Astrophysics Network Potsdam, the Yukawa Institute for Theoretical Physics at Kyoto University, and the University of Maryland[18].
