Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of gravity at very large scales. DESI is an international collaboration of more than 900 researchers, included the Instituto de Astrofísica de Canarias (IAC), from over 70 institutions around the world and is managed by
The Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) have collaborated in the research that reveals the structure of 74 exocomet belts, it means, belts with minor bodies outside our solar system, around stars close to us. Astrophysicists led by a team from Trinity College Dublin , with the Universidad de La Laguna (ULL) and Instituto de Aastrofísica de Canarias (IAC) collaboration- have for the first time imaged a large number of exocomet belts around nearby stars, and the tiny pebbles within them. The crystal-clear images show light being emitted from these
