The centres of massive galaxies are among the most exotic regions in the Universe. They harbour supermassive black holes, with masses of at least one million, and reaching thousands of millions of times the mass of the Sun. These black holes can cause a great deal of matter to fall towards them, producing the emission of huge quantities of energy before they finally fall into the black hole. Also, during this period (the "active phase" of the galaxy, referred to as an AGN or Active Galactic Nucleus) matter is expelled from outside the black hole in the form of high velocity (relativistic)

The Instituto de Astrofísica de Canarias hosts a panel debate about ways for economic and social growth, with Leif Edvinsson and Günter Koch, experts on intelectual capital.

This project, in which the Instituto de Astrofísica de Canarias (IAC) is collaborating, has made a map with 300 galaxies close to the Milky Way, which they have classified on the basis of the way the stars are moving, rather than using the morphological classification used until now.

An international team of astronomers led by Giuseppina Battaglia, researcher at the Instituto de Astrofísica de Canarias (IAC), finds signs that the outer halo of the Milky Way contains stellar remains of massive dwarf galaxies that were devoured by our own.

An international team of astronomers with participation of researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has revealed an ‘astonishing’ overabundance of massive stars in a neighbouring galaxy.
