  • An international team, including researchers from the Instituto de Astrofísica de Canarias (IAC), used combined data from different radio telescopes located in Spain to probe the mode of star formation in a galaxy when the universe had less than 30% of its current age. They revealed that the properties of the molecular gas reservoir are similar to the one of our own Galaxy, unseen up to now in the distant universe. The paper is published in the Astrophysical Journal Letters. A major question in the study of galaxies is on the mode of star formation, how efficient the conversion of cold gas

  • Why does gravity have the strength it has? What exactly determines the value of the electromagnetic force? Are the laws of Physics the same in any part of the universe and at any instant in time? Measurements made with the ESPRESSO high resolution spectrograph on the Very Large Telescope (VLT) have permitted the determination of one of the fundamental constants of Physics when the universe was only 40% of its present age, helping to find an answer to one of these questions. The study, in which a leading group of researchers from the Instituto de Astrofísica de Canarias (IAC) participated, is

  • An international team, including researchers from the Instituto de Astrofísica de Canarias (IAC), has discovered an extrasolar planet with half the mass of the Earth that takes approximately eight hours to orbit its parent star, a red dwarf just under 31 light-years from Earth. Called GJ 367 b, it is one of the lightest among the nearly 5.000 exoplanets known today. With a diameter of just over 9000 kilometres, this sub-Earth is slightly larger than Mars. The discovery not only demonstrates that it is possible to precisely determine the event the smallest, least massive exoplanets, but also

  • An international team of scientists, in which researchers from the Instituto de Astrofísica de Canarias (IAC) participate together with other institutions from Spain, Italy, Germany, Belgium, UK, and Mexico, has been able to measure the masses of the giant planets of the V1298 Tau system, just 20 million year old. Masses for such young giant planets had not been obtained previously, and this is the first evidence that these objects have already reached their final size at very early stages of their evolution. For this study they have used radial velocity measurements from the HARPS-N

  • 65 doctoral students and postgraduate researchers from 15 different countries participated, for 9 days, in the XXXII Canary Islands Winter School of Astrophysics, which this year was focused on clusters of galaxies, the largest gravitationally bound structures that we can observe in the Universe. Of the full complement of students, 55 were present at the school, while the other 10 followed the course on internet. As well as being one fo the first astrophysics meetings celebrated internationally with students present, this edition of the IAC Winter School was noteworthy for the highest

  • In December 2020 a team from the European Space Agency (ESA) published an image taken by the Hubble Space Telescope (HST) of GAL-CLUS-022058s, the biggest and one of the most complete Einstein rings discovered, situated towards the southern hemisphere constellation of Fornax. Since then, those observations have been used to develop a model of gravitational lenses which has enabled the study of the physical properties of the amplified galaxies.
