    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

    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.

    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

  • Artistic rendition of the re-ionisation process. Each dot is a galaxy, which ionises its surroundings forming a bubble. These bubbles can grow depending of the ionising power of each galaxy. If the galaxies are close together the bubbles can merge and form a much larger bubble. With time all the bubbles will merge till the Universe become re-ionised. Ionisation is the process under which high energy photons from the galaxies kick out the electron from the neutral hydrogen atoms thus leaving them ionised.
    We show herein that a proto-cluster of Lyα emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionising continuum photons. We start from the Lyα fluxes measured in the spectra of the sources detected spectroscopically. From these fluxes we derive the ionising emissivity of continuum photons of the proto-cluster, which we compare with the ionising emissivity required to reionise the proto-cluster volume. We find that the sources in the proto-cluster are capable of ionising a large bubble, indeed larger than the volume occupied by the proto-cluster
