An interview of the Bonner General-Anzeiger vom April 28 2025: “Proposal for a Cluster of Excellence: Astronomers want to explore new dimensions of simulating depth” by Martin Wein.  

An international team of astronomers from the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in India, the University of Bonn, and the Ioffe Institute in St. Petersburg, Russia, has surveyed the cold gas in the Milky Way using the most sensitive radio telescope on Earth—the MeerKAT telescope in South Africa. The "MeerKAT Absorption Line Survey" (MALS) is the most comprehensive published catalog of its kind to date. Astronomers are using the MALS survey to understand why the Milky Way continues to form new stars, even though it is billions of years old. The study has been accepted for publication in the journal Astronomy & Astrophysics, and a preprint is available at http://arxiv.org/abs/2504.00097.

Germany’s members of the Euclid Consortium have played a significant role in producing the mission’s first large set of survey data which the European Space Agency has just released.

The scientific article published by Nature Astronomy concisely outlines the principal domains where X-ray astronomy is anticipated to advance our comprehension of the Universe in the forthcoming decade. 

Astrochemist Professor Serena Viti appointed designated Hertz Professor at the University of Bonn.

On 15 October 2024, ESA’s Euclid space mission reveals the first piece of its great map of the Universe, showing millions of stars and galaxies. The captured strip across the sky demonstrates the stunning data quality at all levels, from wide-angle views of the Universe to the details of structures inside individual galaxies. Several German research institutes are involved in this ground-breaking mission, and the scientists and engineers are thrilled to see these results.

Today, the Euclid Consortium publishes the first scientific results on observations with the Euclid space telescope.

Results from the first Erosita X-Ray sky survey show consistency where previous measurements of the structure of the universe indicated inconsistencies. The analysis of how galaxy clusters, the largest objects in the Universe, evolve over cosmic time has yielded precise measurements of the total matter content and its clumpiness, report scientists of the German eROSITA consortium, led by the Max Planck Institute for Extraterrestrial Physics and with participation of the University of Bonn. The results affirm the standard cosmological model and alleviate the so-called S8 tension, while at the same time offering insights into the elusive neutrinos' mass. The analysis is based on one of the largest catalogues of galaxy clusters and superclusters, also released today. An important pillar in the analysis is the ``weighing’’ of the discovered galaxy clusters, where the University of Bonn contributed in a major way.
