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 detectionAdvertised on

The first batch of data from the Dark Energy Spectroscopic Instrument is now available for researchers to mine. Taken during the experiment’s “survey validation” phase, the data include distant galaxies and quasars as well as Milky Way stars. The universe is big, and it’s getting bigger. To study dark energy, the mysterious force behind the accelerating expansion of our universe, scientists are using the Dark Energy Spectroscopic Instrument (DESI) to map more than 40 million galaxies, quasars, and stars. Today, the collaboration, which includes the Instituto de Astrofísica de Canarias (IAC)Advertised on

Research, in which the Instituto de Astrofísica de Canarias has participated has analyzed object 2023 FY3, a member of a group of asteroids which have trajectories similar to that of the Earth. The available data suggest that it could collide with the Earth during the next hundred years, but its small size implies that it is not a major threat The study of the physical characteristics and the dynamical evolution of object 2023 FY3, in which the Instituto de Astrofísica de Canarias (IAC) and the Complutense University of Madrid (UCM) have participated, enhances our limited knowledge about theAdvertised on
