    In the document presenting the General National Budget for 2021 approved by the Council of Ministers for 2021, the Instituto de Astrofísica de Canarias (IAC) will receive, next year, a sum of 9 million euros from the State Plan of Investments and Reforms. This extraordinary grant, which will be spent on investments and technological infrastructure, is in addition to the annual grant from the Ministry of Science and Innovation. The IAC is thereby recognized as a powerful motor attracting external funding to the Canaries to drive technological development and create employment.

  • Dark matter in two galaxies simulated on a computer. The only difference between them is the nature of dark matter. Without collisions on the left and with collisions on the right. The work suggests that dark matter in real galaxies looks more like the image on the right, less clumpy and more diffuse than the one on the left. The circle marks the end of the galaxy.

    The gravitational force in the Universe under which it has evolved from a state almost uniform at the Big Bang until now, when matter is concentrated in galaxies, stars and planets, is provided by what is termed ‘dark matter’. But in spite of the essential role that this extra material plays, we know almost nothing about its nature, behaviour and composition, which is one of the basic problems of modern physics. In a recent article in Astronomy & Astrophysics Letters, scientists at the Instituto de Astrofísica de Canarias (IAC)/University of La Laguna (ULL) and of the National University of

    An international team of astronomers has identified one of the rarest known classes of gamma-ray emitting galaxies, called BL Lacertae, within the first 2 billion years of the age of the Universe. The team, that has used one of the largest optical telescope in the world, Gran Telescopio Canarias (GTC), located at the Observatorio del Roque de los Muchachos (Garafía, La Palma), consists of researchers from the Universidad Complutense de Madrid (UCM, Spain), DESY (Germany), University of California Riverside and Clemson University (USA). The finding is published in The Astrophysical Journal

  • AU mic b light curves from TESS and Spitzer IRAC at 4.5 μm  (purple filled circles). The transit model (orange curve) includes a photometric model that accounts for the stellar activity modelled with a Gaussian Process (GP), which is subtracted from the data before plotting. The frequent flares from the stellar surface are removed with an iterative sigma-clipping.

    AU Microscopii (AU Mic) is the second closest pre-main-sequence star, at a distance of 9.79 parsecs and with an age of 22 million years. AU Mic possesses a relatively rare and spatially resolved edge-on debris disk extending from about 35 to 210 astronomical units from the star, and with clumps exhibiting non-Keplerian motion. Detection of newly formed planets around such a star is challenged by the presence of spots, plage, flares and other manifestations of magnetic ‘activity’ on the star. Here we report observations of a planet transiting AU Mic. The transiting planet, AU Mic b, has an

    The Instituto de Astrofísica de Canarias (IAC) has finished, during October, with the help of FEDER funds, the renewal of the corporate network of the Canary Observatories, which means that the connected User Institutions will be able, with the new equipment, to augment their current connection capacity from 1 Gbps to 10 Gbps.

    The first tests of a concept using microwave radiometry have yielded promising results for the measurement of subcutaneous temperatures in biological tissues. The prototype has been developed in the programme of Medical Technology within IACTEC, the area of technological and business collaboration of the Instituto de Astrofísica de Canarias (IAC) with economic support (Training Programme) and infrastructure (the IACTEC building) from the Cabildo of Tenerife.
