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)

Heidelberg researchers have run the largest simulation of the formation and evolution of massive galaxy clusters. Now the simulation data have been published in full, so that others can also use it for their research. (2025/03/05)

Dominika Wylezalek has been appointed as a new Professor at ZAH and Director at ARI, effective March 1, 2025. She will lead the research group “Galaxy Evolution and AGN (GALENA)”. (2025/02/24)
