# Research at the Albert Einstein Institute

### Astrophysical and Cosmological Relativity (Potsdam)

The research carried out in the department

*Astrophysical and Cosmological Relativity*, led by Alessandra Buonanno, aims at developing accurate analytical and numerical models of gravitational-wave sources, improving our ability to extract unique astrophysical and cosmological information from the observed waveforms, and testing Einstein’s theory of general relativity. [more]### Computational Relativistic Astrophysics (Potsdam)

Research of the division

*Computational Relativistic Astrophysics*, led by Masaru Shibata, covers mergers of binary neutron stars and mixed binaries – binary systems of a black hole and a neutron star – as well as stellar core collapse that form black holes. The division also focuses on studying more fundamental aspects of General Relativity using numerical tools. [more]### Quantum Gravity and Unified Theories (Potsdam)

The department

*Quantum Gravity and Unified Theories*, led by Hermann Nicolai, attends to the development of a theory that unifies quantum theory and general relativity - in the framework of superstring theory as well as canonical quantization. [more]### Laser Interferometry and Gravitational Wave Astronomy (Hannover)

Led by Karsten Danzmann, the division

*Laser Interferometry and Gravitational Wave Astronomy*focuses on the development of gravitational wave detectors on Earth as well as in Space. This comprises also a full range of supporting laboratory experiments in quantum optics and laser physics. [more]### Observational Relativity and Cosmology (Hannover)

The

*Observational Relativity and Cosmology*division, led by Bruce Allen, focuses on direct observational consequences of General Relativity, including the search/analysis of gravitational wave (GW) data, and operation of the Einstein@Home project, looking for weak radio, gamma-ray and GW signals from spinning neutron stars. [more]### Independent Research Groups

The AEI in Potsdam hosts five independent research groups including a permanent one that specializes in geometry and gravitation. The other independent research groups ar working on black hole theory, theoretical cosmology, quantum fields and information, and in history of quantum gravity (in collaboration with the MPI for the History of Science in Berlin). AEI Hannover hosts three independent research groups: one is permanent and is working on continuous gravitational waves, another one works on binary merger observations and numerical relativity, and the third one is a Lise Meitner Group focusing on gravitational theory and cosmology.

### Director Emeritus B.F. Schutz (Potsdam)

Bernard Schutz is one of the founding directors of the Max Planck Institute for Gravitational Physics. As director of the

*Astrophysical Relativity*department from 1994 until his retirement in 2014 he played a major role in building up the Institute. [more]### Independent research groups (Hannover)

### Independent research groups (Potsdam)

The AEI in Potsdam-Golm hosts four independent research groups that specialize in black hole theory, theoretical cosmology, and quantum fields and information. These groups cooperate closely with the divisions at the AEI. [more]
