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 theoriesAdvertised on -
The members of the Comité Científico Internacional (CCI) of the Canary Islands Observatories met today on the island of La Palma. The ISC is the body established in the International Agreements that gave rise to the Canary Islands Observatories managed by the Instituto de Astrofísica de Canarias (IAC) and guarantees the effective participation of the User Institutions in decision-making regarding their use, maintenance and improvement. The meeting, held at the Hotel H10 Taburiente Playa, began with a minute's silence in memory of Professor Francisco Sánchez, founder of the IAC, whose legacyAdvertised on -
A multidisciplinary team of astrophysicists, neuroscientists, engineers, and musicians has unveiled a pioneering method to “listen” to the structure of the human brain. Published in Nature Scientific Reports , the study presents the first higher-order sonification applied to structural magnetic resonance imaging (MRI) data. This technique involves transforming three-dimensional information about the brain into sound, taking into account the spatial relationships and complex structure of the data. To do this, mathematical tools originally developed to study the large-scale structure of theAdvertised on
