Omega Centauri is a large globular cluster, containing almost ten million stars, in the direction of the constellation of Centaurus, which has been studied to understand its stellar kinematics, the motions of its stars under the action of the gravitational forces which act on them. A research team at the Instituto de Astrofísica de Canarias (IAC) has just published a study which shows that a group of black holes dominates the movements of its stellar kinematics. This result can be extended to certain other structures in the universe and goes against some previous claims about the role of low

The Instituto de Astrofísica de Canarias (IAC) is demonstrating the quality and international relevance of the Canary Islands Observatories at the 245th session of the American Astronomical Society (AAS) meeting being held this week in Maryland (USA). This meeting, led by the American astrophysics community, brings together the world's most important research centres in this field to share lines of work and proposals for the present and the future. The IAC delegation in Maryland is headed by the director of the centre, Valentín Martínez Pillet, who is part of the panel of speakers with a

UNDARK is a pioneering project led by the Instituto de Astrofísica de Canarias (IAC) bringing together outstanding international institutions in the fields of astrophysics, cosmology, and particle physics. Funded for three years via the 'Widening' programme of the European Union, its objective is to tackle one of the major puzzles of contemporary physics: the dark universe. The major part of the Cosmos is composed by the so-called “dark universe”. Barely 18% of the total matter in the universe is made up of the elements in atoms with which we are familiar, while the remaining 82%, termed
