Galaxy clusters represent the largest gravitationally bound systems in the Universe, formed by the hierarchical assembly of dark-matter haloes and the baryonic gas that accumulates within them. The ...

Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA), the team's findings, published on March 13 in The Astrophysical Journal Letters, show that turbulent conditions in the ...

Star clusters arise within the densest cores of molecular clouds, where gravity drives the collapse of gas and dust to form stars nearly simultaneously. Their formation is regulated by the complex ...

A study published in Astronomy & Astrophysics has identified four previously unknown primordial open cluster (OC) groups in the Milky Way. Open clusters, loose assemblies of stars born from the same ...

On the left, an artist’s impression of a globular cluster near its birth, hosting extremely massive stars with powerful stellar winds that enrich the cluster with elements processed at extremely high ...
