    The cultural and sky landscape of the Way of Saint James
    A study led by the researcher of the Instituto de Astrofísica de Canarias Maitane Urrutia-Aparicio has shown the relevance of sunrise on Easter Sunday, one of the most important Christian festivities, in the orientation of Romanesque churches on the Camino de Santiago. This work exposes the close relationship between the sky and the orientation of the constructions of the Jacobean Route. It also shows that medieval societies already included temporal symbolism in the construction of their temples. The latest research results have been published in the journal Sustainability.

  • Spectra obtained with ESPRESSO, corresponding to three different transitions in an absorbing system at z=1.15 towards the quasar HE0515-4414, compared with previous spectra on the same object obtained with the UVES and HARPS spectrographs, at lower spectral resolution.

    Testing fundamental physics with ESPRESSO
    Many of the most basic and important physical phenomena are determined by a set of “fundamental constants”, whose values are experimentally known to high accuracy. A key aspect is to know whether they are “universal constants”, i.e., whether they have always had the same value across the Universe and throughout its history . Here we made use of data from the ESPRESSO spectrograph on the Very Large Telescope (VLT) in order to determine the value of the fine structure constant 8 thousand million years ago (when the Universe was just 40% its current age) by measuring spectral transitions in a

    MAGIC Telescope System detects energetic nuclear blast from vampire star
    Scientists from the MAGIC collaboration, using a system of two 17m diameter imaging air Cherenkov telescopes located on the Canary Island of La Palma, Spain, have detected very high energy gamma-rays from a recurrent nova in the Milky Way. This event is the first one that has been detected at such energies and may provide new insight into this class of eruptions, and the potential role they play for producing the mysterious highly energetic cosmic rays that permeate the Milky Way. The researchers present the results of their observations and insights they gained into this type of stellar

    BBVA Foundation's president, Carlos Torres Vila, visits the Roque de los Muchachos Observatory
    The president of the BBVA Foundation, Carlos Torres Vila, visited the Roque de los Muchachos Observatory (Garafía, La Palma) to learn about the work being done by the Instituto de Astrofísica de Canarias (IAC). The most recent collaboration between the two institutions has been a research project led by astronomer Johan Knapen Koelstra and funded by the BBVA Foundation as part of its Programa de Ayudas a Equipos de Investigación en el área de Big Data. The president of the Foundation visited the GTC and the Cherenkov telescopes (MAGIC and LST), where he received explanations on the progress

  • Validación Principio de Equivalencia - Cúmulo de estrellas
    IAC scientists obtain one of the most general validations of Einstein’s Principle of Equivalence
    The study shows the potential of major astronomical observatories to test the laws of physics and to show their universal character. The results are published in The Astrophysical Journal The General Theory of Relativity is one of the basic pillars of modern physics. One of the bases which support Einstein`s theory is the Principle of Equivalence. Using this principle one can infer that light which escapes from a region with a strong gravitational field loses energy as it travels, so that its wavelength shifts to the red. This phenomenon is known as the gravitational redshift, and measuring

    The IAC and the AEMET sign a collaboration agreement
    The Instituto de Astrofísica de Canarias (IAC) and the National Meteorological Agency (AEMET) have stengthened their commitment to collaborate by adpoting measures which allow them to share installations, services, and data from their observatories. The agreement also contains clauses oriented to the ecological transition, energy use optimizaiton, the reduction of light pollution and assurance of the environmental quality of Izaña. The Instituto de Astrofísica de Canarias (IAC) and the National Meteorological Agency (AEMET) which depends on the Ministry for Ecological Transition and
