    Pedro Duque attends the “official opening” of IACTEC and presides over the Governing Council of the IAC
    The Minister of Science and Innovation this morning presided over the annual meeting of the Governing Council of the Instituto de Astrofísica de Canarias (IAC) after the “official opening” of the installations of IACTEC in La Laguna, which are fully operational from today. In a press conference he stressed the programmes which will be carried out in the Area of Cooperation Business-Technology, among them the new Centre of Advanced Optical Systems (CSOA). He also reported on the current state of the negotiations regarding the Thirty Meter Telescope (TMT), of greatest international interest

  • Severo Ochoa Centre of Excellence Qualification
    Press release
    The IAC has its qualification as a Severo Ochoa Centre of Excellence renewed
    The Ministry of Science and Innovation published yesterday the provisional resolution of the qualification of the Centres and Units of Excellence, granting the Instituto de Astrofísica de Canarias the recognition as a Centre of Excellence for the third consecutive time. The National Research Agency (AEI for its Spanish initials), which depends on the Ministry of Science and Innovation, has published the provisional resolution awarding the new Qualifications of the Severo Ochoa Centres of Excellence, whose aim is to recognize, reward, and promote high level scientific research at the Spanish

    Tidally trapped pulsations in a close binary star system
    It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have been searched for, but until now never detected. Here we report the discovery of tidally trapped pulsations in the ellipsoidal variable HD 74423 in Transiting Exoplanet Survey Satellite (TESS) space photometry data. The system contains a Delta Scuti pulsator in a 1.6 d orbit, whose pulsation mode amplitude is strongly modulated at the orbital frequency, which can be explained if the pulsations have a much larger amplitude in one

    Press release
    MAGIC telescopes test the quantum structure of space-time
    The detection of a gamma ray burst by the MAGIC telescopes at the Roque de los Muchachos Observatory allows us to study whether the speed of light in a vacuum is a constant in nature. The results, published in the journal Physical Review Letters, indicate that there are no significant differences in the arrival times of photons of different energies, which sets constraints on some quantum theories of gravity.

    Press release
    The structure of the famous Jet of material in M87, the brightest galaxy in the Virgo Cluster, revealed
    A Master’s degree research project at the University of Barcelona (UB), carried out at the Instituto de Astrofísica de Canarias (IAC) by the student Alejandra Yrupe Fresco, currently studying for her doctorate at the Max Planck Institute for Extraterrestrial Physics, in Germany, has revealed the faint nucleus and the structure of the jet of particles in the nuclear region of M87, the brightest galaxy in the Virgo cluster. This project was carried out in collaboration with the IAC researchers Juan Antonio Fernández Ontiveros, Almudena Prieto and José Antonio Acosta Pulido, and was possible
