The Instituto de Astrofísica de Canarias (IAC) announces the arrival of the Astronomy on Tapinternational talk series in Spain, with its very first edition to be held in Tenerife. This outreach initiative, which was created in the United States and has since expanded worldwide, will now take place in the Canary Islands under the name "Astronomy on Tap – Canary Islands” and the local nickname “AstroTragos,” and is carried out within the framework of the EDUCADO and ExGal-Twin projects at IAC. The debut event will be held at the Búho Club (Calle Catedral, 3, La Laguna, Tenerife) on Thursday

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 simulations
