A new study published in Astronomy & Astrophysics unveils a powerful way to determine the size of dark matter haloes—the massive, invisible structures that host galaxies—by simply measuring how large galaxies appear in deep astronomical images. Researchers Ignacio Trujillo and Claudio Dalla Vecchia, from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL), demonstrate that galaxy size can serve as a precise proxy for halo size, offering measurements up to six times more accurate than previous methods. Using the cutting-edge EAGLE cosmological simulationsAdvertised on -
The exhibition, opened at the Museo de las Ciencias de Castilla-La Mancha, brings the search for Earth-like planets closer to the public and displays technological components developed by Spanish centres involved in the mission. The Instituto de Astrofísica de Canarias (IAC) is participating in the temporary exhibition ‘In search of new Earths’, a display dedicated to the European space mission PLATO and to one of the major challenges in astrophysics today: the search for and characterisation of habitable Earth-like planets beyond the Solar System. The exhibition, which can be visited untilAdvertised on -
Especialistas abordarán el impacto de la iluminación artificial excesiva y sus efectos sobre la astronomía, la salud humana y la biodiversidad El Instituto de Astrofísica de Canarias (IAC) y SEO/BirdLife Canarias celebran la conferencia " Contaminación Lumínica: Una Amenaza Silenciosa", una jornada clave para la protección del medio ambiente y el patrimonio científico del archipiélago. La ponencia estará a cargo de Federico de la Paz, técnico del IAC, y Yarci Acosta de Seo/Birdlife, quien desgranará los graves riesgos que el uso ineficiente y descontrolado de la luz artificial supone para laAdvertised on
