Massive black holes from merger events in star clusters

A new study involving Michela Mapelli (ZAH/ITA) and collaborators suggests that the biggest black holes form through violent merging events in densely populated star clusters. (2026/05/08)

Uncovering Hidden Neutron Stars Across the Galaxy

In a new study Zofia Kaczmarek (ZAH/ARI) and colleagues show how the Roman Space Telescope will enable the discovery of quiescent neutron stars. (2026/05/07)
