An international scientific team, including the researchers from the Instituto de Astrofísica de Canarias (IAC) Cristina Ramos Almeida, Patricia Bessiere and Giovanna Speranza, has discovered that quasars, some of the brightest and most powerful objects in the Universe, are mainly ignited by mergers between galaxies. The finding sheds new light, after years of controversy, on what causes the emission of large amounts of energy in the most powerful active nuclei. The research has used observations from the Isaac Newton Telescope (INT) and the William Herschel Telescope (WHT) at the Roque de

International research, with the participation of the Instituto de Astrofísica de Canarias (IAC), reveals that perturbations in the magnetic fields of galaxies may be related to star formation. The study has mapped the magnetic fields of about fifteen galaxies in the vicinity of the Milky Way. The data were obtained with the HAWC+ instrument on board SOFIA, an airborne infrared telescope on a Boeing 747 that was operational until September 2022. The results are published in The Astrophysical Journal. For decades, astronomers have studied the forces that govern the interior of galaxies -

An international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our Universe, called blue supergiants. Although these stars are commonly observed, their origin has been an old puzzle that has been debated for several decades. By simulating novel stellar models and analysing a large data sample in the Large Magellanic Cloud, IAC researchers have found strong evidence that most blue supergiants may have formed from the merger of two stars bound in a binary system. The study is published in the
