    This morning the IV SOLARNET meeting "The Sun from its interior to its outer atmosphere" organized by the Instituto de Astrofísica de Canarias (IAC) began, in Arrecife (Lanzarote). The conference was inaugurated by the IAC researchers Elena Khomenko and Marian Martínez, respectively the chair and co-chair of the Scientific Committe, who are experts in Solar Physics, and welcomed the participants. They were followed by Manuel collados, coordinator of the European SOLARNET programme, which provides the framework for the meeting. In his talk this IAC researcher explained the guidelines of the

    Organized by the Instituto de Astrofísica de Canarias (IAC), and within the framework of the European project SOLARNET, the congress will bring together the scientific community in Solar Physics to discuss the challenges it faces and encourage collaboration between research programs. The event will take place in Arrecife (Lanzarote) during 16th and 20th January.

    “With TIMER we could demonstrate a very beautiful idea: If we measure the ages of the stars that were born in the bar via the secular evolution processes, we can estimate when the galactic disc settled into a dynamically mature state” “In order to understand well how galaxies came to be the way we observe them today we must understand well the effects driven by bars” “With the TIMER demonstration programme we have already shown for one galaxy that secular evolution started 10 billion years ago, and that the structure thus formed is actually old” By Elena Mora (IAC) On nights which are

    The first billion years of cosmic history represents the final frontier in assembling a coherent physical picture of early galaxy formation, and a remarkable progress in this area has been made in the last few years. We have carried out a detailed analysis of a gravitationally lensed galaxy A2744_YD4 at z = 8.38 behind the massive galaxy cluster Abell 2744. The photometric redshift of about 8, estimated from HST, VLT and Spitzer data, was confirmed by the detection of the Ly_alpha line at a redshift of z=8.38 in a deep VLT X-SHOOTER spectrum. The follow-up observations with the Atacama Large

  • GTC/OSIRIS spectrum of BG1429+1202 showing strong Lyman-Alpha emission as well as strong absorptions from its interstellar medium and stellar winds. In insets panels, DECaLS grz color image, GTC g-band, and WHT i-band of BG1429+1202 are shown.
    In the phenomenon of gravitational lensing, predicted by Einstein's General Theory of Relativity, the mass of a galaxy acts on the light of a more distant object, as if it were a huge lens, producing a distorted image with the form of a so-called Einstein ring or multiple images and a magnification of the total flux, allowing to see details which would otherwise be too faint to detect. GTC/OSIRIS spectroscopic observations allowed to discover one of the brightest galaxies in the early Universe, BG1429+1202, located at a redshift of 2.82 (we see it as it was some 2,300 million years after the
