    The IAC and the Observatorios de Canarias will participate in the " European Researchers' Night"
    The Instituto de Astrofísica de Canarias (IAC) and the Observatorios de Canarias will participate during "European Researchers' Night" with live broadcasts via its YOUTUBE channel- IAC Videos- from a number of telescopes at the Teide and Roque de los Muchachos Observatories. Astronomers from diverse disciplines,k (solar physics, high energy astrophysics, galaxies, cosmology..) will show us their work from the most advanced installations: the Gran Telescopio Canarias (GTC) the Quijote Exeriment, the solar towers, the Pyramid, the ESA Optical Ground Station (OGS), the high energy telescopes

    A look at the subatomic world from the IAC
    The second edition of the conference on Particle Physics, HC2NP2019, organized by the Instituto de Astrofísica de Canarias, will take place next week in Puerto de la Cruz. For a week a distinguished gathering of scientists will meet to discuss the latest advances in our understanding of the subatomic world. This, the second edition of the conference "Hadronic Contributions to New Physics Searches" (HC2NP20199, organized by the Instituto de Astrofísica de Canarias (IAC), will take place at the Vallemar Hotel, Puerto de la Cruz. "At the present time" explains Jorge Martín Camalich, a

    Fullerenes in the IC 348 star cluster of the Perseus molecular cloud
    We present the detection of fullerenes C 60 and C 70 in the star-forming region IC 348 of the Perseus molecular cloud. Mid-IR vibrational transitions of C 60 and C 70 in emission are found in Spitzer IRS spectra of individual stars (LRLL 1, 2, 58), in the averaged spectrum of three other cluster stars (LRLL 21, 31, and 67) and in spectra obtained at four interstellar locations distributed across the IC 348 region. Fullerene bands appear widely distributed in this region with higher strength in the lines of sight of stars at the core of the cluster. Emission features consistent with the three

  • The evolutionary phases of galaxies against the dispersion of velocities of the stars (which scales with the total mass). The sample used (gray), the red sequence, green valley and blue cloud are represented. The new definition (left) allows to study in detail the galaxies in the green valley.

    Exploring a new definition of the green valley and its implications
    Galaxy formation remains one of the major open problems in astrophysics today. There is a wide range of mechanisms that control the transformation of gas into stars in galaxies, compounded by the cosmological evolution of structure, along with complex feedback processes. An observational approach targets general trends in large distributions of galaxies. On a diagram plotting colour versus mass, the distribution of galaxies gets split into a bimodal structure, featuring a region of red, passively-evolving galaxies (termed the red sequence), and a so-called blue cloud, made up of star-forming

  • Image, left-hand panel, and reflectance spectrum, right-hand panel, of interstellar comet C/2019 Q4 (Borisov) obtained by the 10.4~m Gran Telescopio Canarias (GTC), located at the El Roque de Los Muchachos Observatory (La Palma, Canary Islands, Spain), which is managed by the Instituto de Astrofísica de Canarias (IAC) together with the Teide Observatory in the island of Tenerife.
    Press release
    The Gran Telescopio Canarias obtains the visible spectrum of C/2019 Q4 (Borisov), the first confirmed interstellar comet
    The spectrum acquired by GTC of interstellar comet C/2019 Q4 (Borisov) reveals that this object has a surface composition not unlike that found in Solar System comets. Shortly before dawn on September 13th, Julia de León, Miquel Serra-Ricart, Javier Licandro, all members of IAC's Solar System Group, and Carlos Raúl de la Fuente Marcos, from the Complutense University of Madrid, obtained high resolution images and visible spectra of comet C/2019 Q4 (Borisov) using the OSIRIS instrument at the 10.4m GTC, installed in the Roque de los Muchachos Observatory (Garafía, La Palma). Observations were
