  • Galaxy cluster in formation

    A study, led by researchers at the Instituto de Astrofísica de Canarias (IAC) and carried out with OSIRIS, an instrument on the Gran Telescopio Canarias (GTC), has found the most densely populated galaxy cluster in formation in the primitive universe. The researchers predict that this structure, which is at a distance of 12.5 billion light years from us, will have evolved becoming a cluster similar to that of Virgo, a neighbour of the Local Group of galaxies to which the Milky Way belongs. The study is published in the specialized journal Monthly Notices of the Royal Astronomical Society

  • Visita secretario Estado España Global

    Ayer visitó las instalaciones del Observatorio del Teide (Tenerife) el secretario de Estado de España Global, Manuel Muñiz, acompañado del delegado del Gobierno en Canarias, Anselmo Pestana, y del subdirector de Gabinete, Guillermo Corral. La subdirectora del Instituto de Astrofísica de Canarias, Casiana Muñoz-Tuñón, y el administrador del Observatorio del Teide, Miquel Serra-Ricart, le hablaron del esfuerzo que se realiza en este centro de investigación y pudieron mostrarle algunos de los telescopios e instrumentos que se encuentran en el Observatorio. Esta visita forma parte de los

    The Instituto de Astrofísica de Canarias (IAC) has led an international team which has developed an algorithm called COSMIC BIRTH to analyse large scale cosmic structures. This new computation method will permit the analysis of the evolution of the structure of dark matter from the early universe until the formation of present day galaxies. This work was recently published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).

  • Solar active region artistic simulation

    Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the outer layers of the solar atmosphere, where the explosive events that occasionally affect the Earth occur. The extraordinary observations of the polarization of the Sun’s ultraviolet light achieved by the CLASP2 mission have made it possible to map the magnetic field throughout the entire solar atmosphere, from the photosphere until the base of the extremely hot corona. This investigation, published today in the journal Science

    A team of astronomers from the National Astronomical Observatory of Japan (NAOJ), with participation by the Instituto de Astrofísica de Canarias (IAC) have tested a method for reconstructing the state of the early Universe applying it to 4,000 simulated universes. To do so they used the ATERUI II supercomputer, at the Japanese observatory and the fastest in the world dedicated to astronomical simulations.

    For astronomers one of the biggest obstacles is the darkness of the Universe itself, above all the darkness caused by the gas and dust which surround active galactic nuclei, or AGN. These nuclei emit a huge quantity of energy produced by the supermassive black hole onto which matter falls at a considerable rate. The accretion processes are fundamental for the evolution of active galaxies. However these nuclei often remain hidden by the dusty structures, called tori, which surround the central black hole. Studyuing the properties of this circumnuclear dust, the accretion processes, and
