# Independent research groups (Hannover)

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.

### Permanent Independent Research Group “Searching for Continuous Gravitational Waves”

The primary goal of the permanent independent research group “Searching for Continuous Gravitational Waves” at the Max Planck Institute for Gravitational Physics is to detect gravitational waves from spinning neutron stars, and thus to observe these stars via a completely different physical mechanism, which would carry important new information about their internal structure and composition.

### Independent Research Group “Binary Merger Observations and Numerical Relativity”

The goal of this Max Planck Independent Research Group is to decipher gravitational-wave observations of merging black holes and neutron stars with the help of our most sophisticated theoretical tool: large-scale numerical simulations of these violent collisions. [more]

### Gravitational Theory and Cosmology

The Lise Meitner Research Group’s primary focus involves applications of mathematical and numerical relativity to study theories of the origin, evolution, and future of the Universe and the relationship to black hole physics and other aspects of gravitational theory. [more]
