A team of researchers from the cosmology group at the Instituto de Astrofísica de Canarias has obtained one of the most accurate measurements of the masses of clusters of galaxies, and of their relation with the amount of hot gas in these clusters. To do this they have studied the dynamics of the galaxies in 570 clusters selected from the catalogue produced by the Planck satellite (ESA). This study has been produced during four years of work, in which over 10,000 spectra have been obtained with the Telescopio Nazionale Galileo (TNG) and the Gran Telescopio Canarias (GTC) at the Roque de los

An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC), has discovered blasts of hot, warm and cold winds from a neutron star consuming matter from a nearby star. The study used a combination of observations made with several telescopes, including the Gran Telescopio Canarias (GTC or Grantecan), located at the Roque de los Muchachos Observatory (Garafía, La Palma). The discovery, published today in the journal Nature, provides new insight into the behaviour of some of the most extreme objects in the Universe. Low-mass X-ray binaries
