Thomas H. Reiprich

Professor Thomas H. Reiprich is a leading astrophysicist at the Argelander Institute for Astronomy, University of Bonn, specializing in X-ray observations of galaxy clusters and large-scale cosmic structure. His research focuses on dark energy, cosmology, and the physics of intergalactic medium through missions like eROSITA.

His primary research interests include:

• Clusters of Galaxies and their evolution
• Supermassive Black Holes and active galactic nuclei
• Cosmological structure formation
• Gravitational lensing phenomena
• X-Ray and Optical Astronomy techniques

Professor Reiprich's recent work has centered on the eROSITA mission, with groundbreaking discoveries including the 15 Mpc intergalactic filament connecting galaxy clusters Abell 3391/95, providing unprecedented evidence of cosmic web structure. His research combines X-ray, radio, and optical data to study the hot gas in cluster outskirts and filaments.

He has been actively involved in public outreach, including lectures at the Planetarium Hamburg and Astronomy on Tap events, making complex cosmological concepts accessible to the general public. His work has received significant media attention from international science outlets including NASA and ESA.

Professor Reiprich maintains an active teaching schedule at the University of Bonn, regularly offering courses on dark energy, galaxy clusters, and X-ray astronomy, for which he and colleague Jürgen Schmitt received the faculty's teaching award for their dark energy lecture in WS15-16.
