  • Quasars interacting with other galaxies

    An international scientific team, including the researchers from the Instituto de Astrofísica de Canarias (IAC) Cristina Ramos Almeida, Patricia Bessiere and Giovanna Speranza, has discovered that quasars, some of the brightest and most powerful objects in the Universe, are mainly ignited by mergers between galaxies. The finding sheds new light, after years of controversy, on what causes the emission of large amounts of energy in the most powerful active nuclei. The research has used observations from the Isaac Newton Telescope (INT) and the William Herschel Telescope (WHT) at the Roque de

  • Galaxia diminuta RX J2129-z95

    Using first-of-their-kind observations from the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, finds a unique, minuscule galaxy that emitted its light more than 13 billion years ago. The galaxy, detected through gravitational lensing, is one of the smallest ever discovered at this distance and has an extremely high star formation rate for its size. This discovery could help astronomers learn more about galaxies that were present shortly after the Universe came into existence. The paper is published in

  • 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

  • World Quantum Day

    El 14 de abril se celebra el Día Mundial de la Tecnología Cuántica que tiene como objetivo involucrar al público en general en la comprensión y el debate de la ciencia y la tecnología cuánticas. La elección del día se realizó como referencia a la constante de Planck, 4.14, valor fundamental en el gobierno de la física cuántica. El Instituto de Astrofísica de Canarias (IAC) lo celebrará con una jornada de difusión de la computación cuántica y sus aplicaciones en el desarrollo de la sociedad del conocimiento, en particular, en el ámbito de las Islas Canarias. El evento tendrá lugar en el

  • DRAGO-2: South Turkmenistan

    The DRAGO-2 instrument, developed by the Instituto de Astrofísica de Canarias (IAC) and launched in January from Cape Canaveral, has sent its first images of the Earth from space, showing a resolution six times better than that of its predecessor DRAGO-1. The space-borne camera DRAGO-2, (Demonstrator for Remote Analysis of Ground Observations), launched into space on January 4th, is the second instrument designed by IACTEC-Space. It observes in the short wavelength infrared, (acronym SWIR), a range invisible to the human eye, but nevertheless very useful for many studies and applications. In

  • 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
