Ultra-faint dwarf galaxies, among the tiniest and faintest galaxies known, may hold the key to understanding one of the Universe’s biggest mysteries: the true nature of dark matter. A new study reveals that even a single collision between dark matter particles every 10 billion years — roughly the age of the Universe — is enough to explain the dark matter cores observed in these small systems. These galaxies, which contain only a few thousand stars, are dominated by dark matter and have relatively simple evolutionary histories. That makes them ideal cosmic laboratories for testing theories

IAC researcher David Aguado has obtained a prestigious Starting Grant from the European Research Council (ERC), aimed at promoting promising young scientists. This is the third ERC grant -one of the most competitive and recognized of the Horizon Europe program- that the center has received so far this year, thus consolidating its international projection. These highly competitive grants provide up to €1.5 million over five years to support outstanding young scientists in establishing their own independent research groups and pursuing pioneering scientific ideas. Searching for the first stars

A greedy white dwarf star in our own Milky Way galaxy is devouring its closest celestial companion at a rate never seen before, according to an international study involving the Instituto de Astrofisica de Canarias (IAC) and the University of La Laguna (ULL). The research, published in the journal Monthly Notices of the Royal Astronomical Society , found the double star, named V Sagittae, is burning unusually bright as the super-dense white dwarf is gorging on its larger twin in a feeding frenzy. Experts think the stars are locked in an "extraterrestrial tango" as they orbit each other every
