  • GTC and Subaru
    A team led by researchers from the Instituto de Astrofísica de Canarias (IAC) and the National Astronomical Observatory of Japan (NAOJ) has made, with the Gran Telescopio Canarias (GTC or Grantecan) and the Subaru telescope, the largest and deepest follow-up to date of a black hole collision previously detected in gravitational waves. The observations showed no optical signal in the direction of the phenomenon, which means that if this black hole merger emitted any light at all, it was fainter than the detection limit of these two telescopes and their instruments. This result imposes an

  • Soup of prebiotic molecules
    A study led by the researcher Susana Iglesias of the Instituto de Astrofísica de Canarias has detected the presence of large quantities of complex organic molecules in one of the nearest star forming regions to the Solar System. The results of this have been published in the journal Monthly Notices of the Royal Astronomical Society. The scientists Susan Iglesias-Groth, of the Instituto de Astrofísica de Canarias (IAC) and Martina Marín-Dobrincic of the Polytechnic University of Cartagena have discovered the presence of numerous prebiotic molecules in the star formation region IC348 of the

  • Spiderweb galaxy
    An international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy. The finding reveals that this protocluster, far from dispersing, will end up gravitationally bound for the rest of its existence. Located at an epoch when the Universe was only 3 billion years old, this is the first time such a hot gas has been detected at such distances. The study, published in Nature, confirms that galaxy clusters, one of the largest known structures in the

    When matter falls into supermassive black holes in the centres of galaxies, it unleashes enormous amounts of energy and is called active galactic nuclei (or AGN). A fraction of AGN release part of this energy as jets that are detectable in radio wavelengths that travel at velocities close to light speed. Our research into the interplay between the jet and the cold gas in the Teacup galaxy helps us to better understand how galaxies evolve. The Teacup is a radio-quiet quasar located 1.3 billion light years from us and its nickname comes from the expanding bubbles seen in the optical and radio

  • Jet blowing bubbles in the Teacup galaxy
    A study led by Anelise Audibert, a researcher at the Instituto de Astrofísica de Canarias (IAC), reveals a process that explains the peculiar morphology of the central region of the Teacup galaxy, a massive quasar located 1.3 billion light-years away from us. This object is characterized by the presence of expanding gas bubbles produced by winds emanating from its central supermassive black hole. The study confirms that a compact jet, only visible at radio waves, is altering the shape and increasing the temperature of the surrounding gas, blowing bubbles that expand laterally. These findings

  • ExoLife Finder (ELF)
    From 13th to 17th of February, in IACTEC, the technical collaboration zone of the Instituto de Astrofísica de Canarias, the first scientific meeting of the Laboratory for Innovation in Optomechanics (LIOM) is taking place. This is a project for the development of new optical and mechanical technology which will form part of the next generaton of telescopes, such as the ExoLife Finder (ELF), aimed at the search for life outside the Solar System. The meeting has brought together 30 specialists in optics and photonics from Europe, Canada, and the United States. During the course of this week
