  • Star cluster Westerlund 1,
    A scientific team led by the University of Alicante, with participation by the Instituto de Astrofísica de Canarias (IAC) has produced a detailed study of the most massive young star cluster in the Milky Way. This cloud of stars contains different types of giant stars in diverse phases of evolution, and can be used as an excellent laboratory for the study of the formation and evolution of massive stars. Stars tend to form in clusters, containing from just a few to several thousand stars, which share the same age and composition, although they show evolutionary differences. Among the clusters

  • According to the current theories of galaxy formation, these generally form as small entities that grow through fusion, collision and accretion, eventually becoming the majestic galaxies that we observe nowadays. As an example of such process we can mention our own galaxy, the Milky Way. Around it we can find tens of dwarf galaxies and even stellar “streams” formed by already dissolved systems. We have focused in the study of our two most prominent satellite galaxies, the Magellanic Clouds, a system in the process of falling towards our Galaxy, whilst also having a mutual interaction. Their

  • visita eurodiputados
    Yesterday May 23rd, a group of Members of the European Parliament belonging to the Regional Development Commission visited the Installations of the Roque de los Muchachos Observatory (ORM). They also were given informatjon about the use of the European Funds for Regional Development which have been used to build world class sceintiric installations such as the Gran Telescopio Canarias, and the telescopes of the CTA (Cherenkov Telescope Array). The visit was in the framework of the visit by the Commisson to the island of La Palma to see directly the consequences of the eruption of the volcano

  • Simulation of the Formation and Evolution of a Cluster of Galaxies
    The Instituto de Astrofísica de Canarias (IAC) has led the development of a new numerical procedure that allows to reproduce in a few seconds with Big Data and machine learning techniques the intergalactic medium obtained from a cosmological simulation of 100,000 hours of computation. Thanks to this algorithm, called Hydro-BAM, researchers have been able to exploit the hierarchy in the relationship between the properties of dark matter, ionized gas and intergalactic neutral hydrogen, ingredients that make up the large-scale structure of our universe. The research has also made it possible to

  • Sculptor dwarf
    The journal Nature Astronomy publishes today, in its collection of reviews dedicated to dwarf galaxies, a new article written by Giuseppina Battaglia, researcher at the Instituto de Astrofísica de Canarias and the University of La Laguna, and Carlo Nipoti, researcher at the University of Bologna. The study describes the latest results on the search for dark matter in Local Group dwarf galaxies. Dark matter in dwarf galaxies is the subject of a review article published today in the journal Nature Astronomy in its living collection of articles that, from December 2021, is dedicated to the

  • Imagen del satélite GAIA
    A team of researchers from the Instituto de Astrofísica de Canarias (IAC) led by Giuseppina Battaglia has used the third catalogue of data, EDR3, from the GAIA satellite which contains astrometric data (positions, proper motions and brightness measurements ) od 1.8 million objects brighter than magnitude 21, to determine the displacements of 73 galaxies belonging tothe Loca Group (our neighbouting galaxies, comprising three spiral galaxies, the Milky Way, (where we are situated), M31 and M33, and a set of small irregial and dwarf galaxies, around a hundred, among which the Magellanic Clouds
