The Instituto de Astrofísica de Canarias (IAC) is demonstrating the quality and international relevance of the Canary Islands Observatories at the 245th session of the American Astronomical Society (AAS) meeting being held this week in Maryland (USA). This meeting, led by the American astrophysics community, brings together the world's most important research centres in this field to share lines of work and proposals for the present and the future. The IAC delegation in Maryland is headed by the director of the centre, Valentín Martínez Pillet, who is part of the panel of speakers with a

Research led by the Instituto de Astrofísica de Canarias (IAC) has used an innovative technique based on artificial intelligence to study how stars form in galaxies. By analysing 10 000 nearby galaxies, the team have discovered that most stars are born within their own galaxy. Galactic mergers, while important, are not the main source of new stars. Furthermore, the study reveals that more massive galaxies are more affected by these mergers. These results, published in Nature Astronomy, provide new clues about the complex history of galaxies and their evolution over time. Most galaxies do not

An international study led by Almudena Prieto, a researcher at the Instituto de Astrofísica de Canarias (IAC) has found places where new stars are forming, as faint star clusters, around the centre of an evolved galaxy. This is the first time that young populations of stars have been picked out and dated in this type of galaxies dominated by very old stars, which can be called “rejuvenated old galaxies”. The research has combined observations from various telescopes, both ground based and space based, and has used innovative techniques of data analysis. The results are published in the
