    A mechanism for removing dark matter from galaxies has been found

    The small fraction of dark matter in the galaxy NGC1052-DF4 has worried the astronomical community for several years. Now a team of researchers from the Instituto de Astrofísica de Canarias (IAAC) the University of La Laguna (ULL) the University of New South Wales, the Insituto de Astrofísica de Andalucia, and NASA’S Ames Research Center have found a mechnism which can esplain it. This finding, which is to be published in the scientific journal The Astrophysical Journal, manages to make this phenomenon fit with accepted models of formation and evolution of galaxies.

    The IAC is collaborating again with the Spanish-American Writers’ Festival in La Palma

    The Instituto de Astrofísica de Canarias (IAC) will be collaborating for the third successive year with the Spanish-American Writers’ Festival which will be celebrated from September 14th to 19th in Los Llanos de Aridane (La Palma). The programme of this third edition, in which almost 40 writers and a small group of meta-writers (editors, journalists and critics) will participate, will consist of 35 sessions. Among them we can pick out panel sessions on a variety of themes, autographs of examples by some of the authors involved, and activities aimed at the younger generation whose schools

  • 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.

    Solved: the mystery of how dark matter in galaxies is distributed

    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
