  • 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

The “reconstruction method” winds back the evolution from right to left on this illustration to reproduce the primordial density fluctuations from the current galaxy distribution.

    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

  • Portada capítulo VII serie Niñas

    La serie audiovisual “Niñas que rompieron un techo de cristal mirando al cielo”, iniciada en 2017 como parte de un proyecto de género del Instituto de Astrofísica de Canarias (IAC), añade un capítulo más (el séptimo) con motivo del “Día Internacional de la Mujer y la Niña en la Ciencia” que se celebra hoy, 11 de febrero. Cada capítulo de la serie recoge en breves declaraciones las historias personales y profesionales de cuatro astrofísicas o ingenieras que trabajan en este centro de investigación. En los vídeos responden a tres preguntas: ¿Qué querían ser cuando eran pequeñas? ¿Qué

  • Spectral energy distribution (in white; best theoretical fit in blue) of an extremely red old star. The photometric data from Spitzer's IRAC and MIPS instruments are represented in purple. Credits: Dell'Agli et al. (2021) with  background infrared image of the Large Magellanic Cloud, NASA/JPL-Caltech/Meixner(STSCI) and the Sage Legacy Team.

    Modelling dust formation in single stars evolving through the carbon-star stage of the asymptotic giant branch (AGB) (i.e., the late evolutionary stages of Sun-like stars) reproduces reasonably well the mid-infrared colours and magnitudes of most of the C-rich sources in low-metallicity galaxies with known distances like the Large Magellanic Cloud (LMC). The only exception to this is a small subset of extremely red objects (EROs). An analysis of the spectral energy distributions of EROs suggests the presence of large quantities of dust, which demand gas densities in the outflow significantly

  • Attendees at the 2017 11F activities in La Laguna

    For a further year the IAC is celebrating the International Day of Women and Girls in Science with activities to encourage the interest of the younger girls in scientific and technological careers. According to the report “ Women scientists in figures, 2017” the proportion of women in the total of the researchers in Spain has no trisen in the past 10 years, holding steady at 39%. But worse, at later stages in the research career this pecentage drops to 29%. In order to redress the balance on December 15th 2015 the General Assembly of the United Nations proclaimed 11th February the
