A study led by researcher Laura Scholz, of the Instituto de Astrofísica de Canarias (IAC) has found, for the first time, observational evidence that the evolution and the properties of the galaxies are conditioned not only by the mass of the stars they contain, but aso by the effect of the dark matter halos which surround them. The results are published in the specialist journal Nature Astronomy. Dark matter comprises around 85% of all the matter in the Universe. Although ordinary matter absorbs, reflects and emits light, dark matter cannot be seen directly, which makes its detection

The first Large-Sized Telescope (LST) prototype of the Cherenkov Telescope Array Observatory (CTAO), located at the Roque de los Muchachos Observatory (Garafía, La Palma), has made its first scientific discovery by detecting the source OP 313 above 100 gigaelectronvolts (GeV), a level of energy a billion times higher than the visible light that humans can perceive. It is the most distant quasar ever observed by gamma-ray instruments from the ground. On 15 December, the Large-Sized Telescope (LST) Collaboration announced through an Astronomer’s Telegram (ATel) the detection of the source OP

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
