  • Severo Ochoa Centre of Excellence Qualification
    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

    The comet NEOWISE from the Canaries

    During the month of July we will be able to see comet c/2020 F3 (NEOWISE) with the naked eye from the Canaries and from the Peninsula.

  • Los telescopios MAGIC en el Observatorio del Roque de los Muchachos
    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.

    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

    Activities for Asteroid Day

    To celebrate Asteroid Day, which commemorates the impact of the Tunguska Fireball in 1908, several researchers from the Instituto de Astrofísica de Canarias (IAC) will participate in on-line chats to talk about the nature of these lesser bodies of the Solar System, and about the risk of impact on the Earth.
