Massive stars in metal-poor galaxies often have close partners, just like the massive stars in our metal-rich Milky Way. This has been discovered by an international scientific team in which research staff from the Instituto de Aastrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) participate. They used the European Very Large Telescope in Chile to monitor the velocity of massive stars in the Small Magellanic Cloud. The research is published in Nature Astronomy . For the past twenty years, astronomers have known that many massive stars in the metal-rich Milky Way have aAdvertised on -
From Thursday, May 8th, to Friday, May 9th, the Canary Islands Institute of Astrophysics (IAC) is hosting the meeting of the Research Advisory Committee (CAI). This is the center's highest advisory body on research and analyzes its scientific and technological output. At this meeting, the director, Valentín Martínez Pillet, will present the center's main scientific and technological milestones, as well as a proposal for future lines of action. The director will also be joined by Eva Villaver, deputy director of the IAC; Romano Corradi, director of Gran Telescopio Canarias; Jonay GonzálezAdvertised on -
An international team led by Cristina Ramos Almeida, a researcher at the Instituto de Astrofísica de Canarias (IAC), has used the James Webb Space Telescope (JWST) to observe five dust-obscured quasars — and the results offer new insights into how galaxies and their central supermassive black holes may evolve. The study is published today in the journal Astronomy & Astrophysics . The energy released by supermassive black holes at the centres of galaxies is a fundamental ingredient in regulating the formation of new stars, and thus galaxy growth. This occurs during an active phase, usuallyAdvertised on
