The ONCE is dedicating its lottery ticket for Sunday, June 29, to the 40th anniversary of the Instituto de Astrofísica de Canarias (IAC). Five and a half million coupons will spread the word about this anniversary throughout Spain, featuring an image of the Gran Telescopio Canarias (GTC or Grantecan), the world's largest optical-infrared telescope, located at the Roque de los Muchachos Observatory (La Palma). Since it began scientific operations in 2009, the GTC has become a symbol of the scientific and technical consolidation of the IAC and the Canary Islands Observatories (OCAN), and its
An international review article in which IAC researcher Jesús Falcón Barroso is a contributor, explains how the study of stellar populations in galaxies outside the Milky Way and the Local Group, using techniques which are called “extragalactic archaeology”, permits the reconstruction of the processes of formation and evolution of those galaxies. This article has been published in the Annual Review of Astronomy & Astrophysics , one of the most prestigious journals in this field, to which only five researchers of the IAC have contributed during the lifetime of the Institute. How did the
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
