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

An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL), has unveiled a breakthrough explanation for the origin of tiny, jet-like plasma ejections in the solar atmosphere, known as “nanojets.” These elusive events which are recently discovered by the NASA’s solar telescopes are thought to play an important role in heating and sustaining the solar corona at temperatures above one million Kelvin. Why Study Nanojets? For decades, solar physicists have been puzzled by the so-called “coronal heating problem.” While the Sun
