    The James Webb telescope produces an unparalleled view of the ghostly light in galaxy clusters
    A recent study, entirely done by researchers at the Instituto de Astrofísica de Canarias (IAC) has produced the most complete analysis to date of the intracluster light, the diffuse and faint light emitted by stars in galaxy clusters which are not gravitationally bound to any galaxy. This result was based on data obtained by the new James Webb Space Telescope (JWST). The research gives new clues about the formation processes of galaxy clusters, and the properties of dark matter. The article was published in the specialized journal The Astrophysical Journal Letters . In clusters of galaxies

    XXXIII Canary Islands Winter School - Overlaps at the Frontiers of Astrophysics, Cosmology and Particle Physics
    From 21th November till 2nd December at the Museo de la Ciencia y el Cosmos (San Cristóbal de La Laguna), and organised by the Instituto de Astrofísica de Canarias The 33rd edition of the Winter School of the Instituto de Astrofísica de Canarias will focus on the efforts of astrophysics, cosmology and particle physics to understand the mysteries of the dark universe. The XXXIII Canary Islands Winter School of Astrophysics, which is taking place between November 21st and December 2nd, was inaugurated yesterday in the Museo de la Ciencia y el Cosmos, with a welcome address by Rafael Rebolo

    The European Space Agency and the Instituto de Astrofísica de Canarias celebrate their silver anniversary in Tenerife
    The workshop “25 years of cooperation in optical technologies and future trends”, will take place next Monday, November 14th, at the Headquarters of the Instituto de Astrofísica de Canarias (IAC) with scientific and engineering staff from the IAC, and from ESTEC, the European Space Technology and Research Centre of the European Space Agency (ESA). At the meeting, the two institutions will present their work on optomechanical engineering and set out the basis for further collaboration. They will discuss, among other subjects, thermal techniques and optical instrumentation developments, cryo

    Unravelling coronal bright points
    When the Sun is observed in X-ray or extreme ultraviolet wavelengths, hundreds of bright and compact structures with a rounded shape and sizes similar to that of our planet Earth can be easily distinguished in the solar corona. These structures are known as Coronal Bright Points or CBPs and they consist of sets of magnetic loops that connect areas of opposite magnetic polarity on the solar surface. These loops confine the solar plasma and in them, by mechanisms that have been debated for many years among solar physicists, the gas remains with temperatures of several million degrees, emitting

    Heaviest element yet detected in an exoplanet atmosphere
    An international team of astronomers, in which IAC researchers participate, have discovered barium, the heaviest element ever found in an exoplanet atmosphere. It has been discovered at high altitudes in the atmosphere of the exoplanets WASP-76 b and WASP-121 b, two ultra-hot gas giants. The unexpected discovery, made possible by the ESPRESSO instrument at the European Southern Observatory's Very Large Telescope (ESO's VLT), raises questions about what these exotic atmospheres may look like. WASP-76 b and WASP-121 b are no ordinary exoplanets. Both are referred to as ultra-hot Jupiters as

    James Webb telescope studies organic molecules near black holes
    Research led by the University of Oxford and with the participation of the Instituto de Astrofísica de Canarias (IAC) has succeeded in studying, for the first time, the tiny dust molecules known as polycyclic aromatic hydrocarbons (PAHs) in the nuclear region of luminous active galaxies. This work is one of the first studies to use spectroscopic data from the James Webb Space Telescope's (JWST) mid-infrared instrument (MIRI). Observing PAH molecules in the innermost regions of the galaxy is one of the best ways to study the influence of the central black hole in the evolution of the host
