Research

We join theoretical models with observations of galaxies, galaxy clusters, and even larger systems. This allows us to infer the structure and history of our Universe. A key aspect is the study of large-scale magnetic fields. Moreover, we develop and maintain databases  and apply machine learning for the analyis of observational data.

• Simulations of cosmic structure formation
• Extragalactic radio observations
• Observational cosmology
• Cosmic magnetic fields
• Probing the early universe with the JWST
• Supermassive black holes
• Discovery of distant quasars
• Machine learning I
• Machine learning II
• Galaxy Clusters Database

We study properties, evolution, and interactions of galaxies in highly detailed simulations and observations. In particular, simulations of the interstellar medium are employed to learn about the interplay of magnetic fields, star formation, supernova feedback, and the synthesis of heavy elements inside galaxies.

• Interstellar medium and star formation
• Simulations of galaxy collisions
• Galaxy evolution

Compact objects, such as white dwarfs and neutron stars, are studied in state-of-the-art simulations to predict gravitational wave signals and the nucleosynthesis of heavy elements. These objecs are related to highly energetic events like novae, supernovae, and gamma ray bursts.

• Gavitational waves from compact binaries
• Origin of heavy elements
• Numerical Relativity
• Time-dependent radiative transfer

Radiative transfer simulations help us to unravel the atmospheric structure, activity, and variability of stars. Another challenge are the detection of extrasolar planets and simulations of their formation and dynamics.

• Protoplanetary disks
• Orbital dynamics near massive stars & binaries
• Stellar and planetary atmospheres
• Stellar activity, young stars & exoplanets

The foundation of the Observatory was a milestone in the development of scientific institutions in Hamburg. We also contribute to research about the history of science and technology.
