    Young stars found in the oldest and most massive galaxies in the Universe
    Elliptical and lenticular galaxies (collectively called early-type galaxies) are the oldest and most massive galaxies in the Universe. These galaxies were built up rapidly (in less than thousand million years) and therefore, their stars are generally ancient and cool, meaning that they mainly shine in the optical and infrared spectral ranges. However, any hot young stars that might be present are difficult to detect in these spectral ranges. The study, based on 30,000 early-type galaxy spectra from the Sloan Digital Sky Survey BOSS has analysed the UV spectral range to detect the young

    Public version of PORTA, a novel 3D radiative transfer code
    The POLMAG research team of the Instituto de Astrofísica de Canarias (IAC), which includes scientists from other international institutions, has released the public version of PORTA, an advanced radiative transfer code to solve the problem of the generation and transfer of polarized radiation in realistic three-dimensional (3D) models of stellar atmospheres. PORTA allows scientists to plan and model spectropolarimetric observations with today’s telescopes. This public version of PORTA offered to the astrophysical community comes with several modules useful for considering several problems of

    The IAC joins the cultural and educational initiatives to help confront Covid-19 with the campaign "#IACUniversoEnCasa"
    Confronted by the health emergency generated by COVID-19, the Instituto de Astrofísica de Canarias (IAC) wants to help by letting the citizen’s responsibility implied by staying at home be an opportunity to bring everyone closer to astronomy and knowledge of the universe, as well as continuing to offer training and support to the educational community, which is carrying on with its work by Internet. With this objective, we at the Press and Outreach Unit (UC3) have set in motion a plan of activities with the name "#IACUniversoEnCasa" (IAC Universe at Home) about which we will be issuing

    Arte y Ciencia I: La fórmula del lápiz
    Ciencia y arte son los dos grandes generadores de saber, los mayores transformadores de la sociedad y sus individuos. Mientras el arte intuye el desorden del mundo, la ciencia ordena y reordena. El amor entre ambas disciplinas ha existido hasta hace pocos siglos.La revolución industrial y la obcecada especialización del conocimiento hizo que ambos mundos llegaran a malinterpretarse e, incluso, despreciarse mutuamente. Los científicos deniegan el arte como fuente de conocimiento y los artistas consideran a la ciencia impersonal e inadecuada. Sin embargo, ciencia y arte no se encuentran tan

    Scientists discover the first pulsating white dwarf in an eclipsing binary system
    An international research, led by scientists from the University of Sheffield and with the participation of the Instituto de Astrofísica de Canarias, has discovered, using the HiPERCAM instrument of the Gran Telescopio Canarias at the Roque de los Muchachos Observatory (Garafía, La Palma), an ancient pulsating star in a double star system. The discovery, which is published in the journal Nature Astronomy, provides important information about how stars like our Sun evolve and eventually die.

    The IAC presents the video of the POLMAG project
    The IAC presents a public outreach video about the project “Polarized Radiation Diagnostics for Exploring the Magnetism of the Outer Solar Atmosphere” (POLMAG). In this video, several POLMAG scientists explain the basic aspects of the project. The POLMAG research group was created in January 2018 within the framework of the Advanced Grant awarded by the European Research Council (ERC) to Javier Trujillo Bueno (CSIC Research Professor and IAC Senior Scientist). POLMAG aims at novel advances in the development and application of polarized radiation diagnostic methods for exploring the magnetic
