The European Research Council (ERC) awarded Michela Mapelli (ZAH/ITA) an Advanced Grant of €2.5 million to study the formation of intermediate-mass black holes with 100 to 10.000 times the mass of our Sun. (2025/06/17)

Dominika Wylezalek (ZAH/ARI) on how a large-scale industrial project is threatening scientific research with telescopes operated by the European Southern Observatory. (2025/05/27)

The findings of a team of astronomers lead by Varsha Ramachandran (ZAH/ARI) reshape our understanding of this iconic cosmic duo. Both the black hole and its companion star are significantly lighter than previously thought. (2025/05/26)

A team of astronomers, including Matteo Maturi from ZAH/ITA, released a catalog of galaxy groups with an unprecedented view into the large-scale structure of the Universe. (2025/05/19)

A groundbreaking study has mapped the full range of turbulent energy across scales in a simulation of the ISM with unprecedented numerical resolution. Ralf Klessen (ZAH/ITA) is one of the main contributors. (2025/05/13)

A new study by the CARMENES project shows that very low-mass stars are likely to host Earth-like planets. On average, there are about two per star. The results have now been published in Astronomy & Astrophysics. (2025/04/28)
