A team of cosmologists from the Institute of Astrophysics of Andalusia (IAA-CSIC) and the Institute of Astrophysics of the Canary Islands (IAC) has obtained the most accurate census to date of the dark matter halos of the Universe. The work is based on the development of a new model, called GPS+, capable of predicting how many dark matter halos exist at each stage of cosmic history. In the universe, there are enormous invisible structures surrounding galaxies and galaxy clusters. These are dark matter halos, concentrations of matter that do not emit light and cannot be directly observed, but

The Instituto de Astrofísica de Canarias (IAC) is taking part in an international study, published in the journal "Science", which provides the first conclusive evidence of a planet’s influence on the behaviour of its star. The results have made it possible to detect and estimate the strength of the magnetic field of the exoplanet GJ 436 b, opening up a new avenue for studying the habitability of planets outside the Solar System. Magnetic fields play a fundamental role in the habitability of planets. On Earth, the magnetic field acts as a shield against the solar wind and contributes to the
