  • RGB image of PSZ1 G158.34-47.49, one of the clusters studied, which has a spectroscopic redshift z=0.311. In the image you can see a gravitational lens arc. The photometric image was taken with ACAM/WHT; the spectroscopic data are from DOLORES/TNG.
    IAC Scientists have characterized over 200 new clusters of galaxies first detected by the Planck satellite using the telescopes on La Palma

    An international team led by the group of Cosmology with Galaxy Clusters of the Instituto de Astrofísica de Canarias (IAC), including researchers from the University of Paris-Saclay (France) and the Max Planck Institute for Extraterrestrial Physics (Garching, Germany) has finished the optical characterization of new clusters of galaxies in the northern hemisphere, detected first by the Planck satellite using tjhe Suyaev-Zel’dovich signal. These studies allow more accurate determination of the mean matter density in the universe and other cosmological parameters. The observations, which have

    A chromospheric resonance cavity in a sunspot mapped with seismology

    Sunspots are intense collections of magnetic fields that pierce through the Sun’s photosphere, with their signatures extending upwards into the outermost extremities of the solar corona. Cutting-edge observations and simulations are providing insights into the underlying wave generation, configuration and damping mechanisms found in sunspot atmospheres. However, the in situ amplification of magnetohydrodynamic waves, rising from a few hundreds of metres per second in the photosphere to several kilometres per second in the chromosphere, has, until now, proved difficult to explain.

    The IAC is designing and making material for protection against COVID-19

    The Technology Division of the Instituto de Astrofísica de Canarias (IAC) has started to design and manufacture protective screens and other sanitary material to shield against the COVID-19 virus. At the request of a number of institutions, the Department of Mechanical Engineering at the IAC has designed a protective screen, which, after receiving the approval of a prototype, has started to be manufactured in series in the Mechanical Workshop of the IAC in La Laguna. At the time of writing, a total of 150 units has been distributed to the City Council of San Cristóbal de La Laguna, and the

    Lyrids 2020: wishes through the window

    On the night of 21st April we will be treated to the maximum of the Lyrids meteor shower. Just as for the other recent astronomical events we will have to see them from home, so that we will need to be very patient, because they will appear with a frequency of barely one every 10 or 15 minutes.

    The CHEOPS mission, in which the IAC is participating, observes its first exoplanets

    CHEOPS, the new exoplanet mission of the European Space Agency (ESA) in coordination with Switzerland, in which the Instituto de Astrofísica de Canarias (IAC) is participating along with other European instituttions, has successfully complete its almost three month period of the verification and calibration of its instrument, with better results than expected. Astrophysicists from the IAC are leading a group of researchers and engineers who recommend the type of observations to monitor the behaviour of the satellite during its time in space and, as part of the science team, participate in
