    A team of astronomers led by ICE-CSIC analyzed for the first time a long radio-observation of a scallop-shell star in a pioneer study. The team observed the star using the Giant Metrewave Radio Telescope (GMRT) located in Pune (India), and related it to the photometric information from NASA’s Transiting Exoplanet Survey Satellite (TESS) and Las Cumbres Global Telescope Observatory. Scallop-shell stars are a recently discovered class of young M dwarfs. More than 70% of the stars in the Milky Way are M dwarfs, although there are only around 50 recently confirmed scallop-shell stars. They show

  • Recreation of a burst, identified as CSS161010, in which a small black hole swallows a star. Credits: Gabriel Pérez (IAC)
    The team led by Claudia Gutiérrez from the ICE-CSIC and IEEC has used the Gran Telescopio Canarias (GTC) and the Nordic Optical Telescope (NOT), at the Roque de Los Muchachos Observatory, of the Instituto de Astrofísica de Canarias (IAC), in La Palma. The CSS161010 burst reached its maximum brightness in just 4 days in a small galaxy 500 million light-years away from us. An international scientific team, led by the Institute of Space Studies of Catalonia (IEEC) and the Institute of Space Sciences (ICE-CSIC), has managed to detect an exceptionally fast and bright cosmic burst in a small

  • Relación entre la SFR media para las galaxias con y sin AGN
    Recent observational studies suggest that feedback from active galactic nuclei (AGNs)—the energetic centres powered by supermassive black holes—may play an important role in the formation and evolution of dwarf galaxies, contrary to the standard thought. We investigated this using two sets of 12 cosmological magnetohydrodynamic simulations of the formation of dwarf galaxies: one set using a version of the AURIGA galaxy formation physics model including AGN feedback and a parallel set with AGN feedback turned off. Our results reveal that AGNs can suppress the star formation (SF) of dwarf

  • Omega Centauri
    Omega Centauri is a large globular cluster, containing almost ten million stars, in the direction of the constellation of Centaurus, which has been studied to understand its stellar kinematics, the motions of its stars under the action of the gravitational forces which act on them. A research team at the Instituto de Astrofísica de Canarias (IAC) has just published a study which shows that a group of black holes dominates the movements of its stellar kinematics. This result can be extended to certain other structures in the universe and goes against some previous claims about the role of low

    The Instituto de Astrofísica de Andalucía (IAA-CSIC) in collaboration with the Instituto de Astrofísica de Canarias (IAC), is promoting the LPI (La Palma Interferometer) project whose aim is to make astronomical observations with an angular resolution a thousand times better than that of the Hubble and the James Webb telescopes. The LPI project has collaboration with various centres of research, and other institutions in Spain, Italy, the nordic countries and Mexic who are working together to build a scientific installation which will be a reference at international level.

    A team of researchers from the Instituto de Astrofísica de Canarias (IAC), collaborating with other international institutions, has managed to find new galaxies in the Spiderweb protocluster. This was possible thanks to the James Webb Space Telescope, which is a project of the space agencies of the United States (NASA), Europe (ESA) and Canada (CSA). Exploring the populations of galaxies, and discovering their physical properties in large scale structures helps astronomers to understand galaxy formation and how their assembly is determined by their environment. The “ Spiderweb” protocluster
