    The Sunrise III mission obtains data from the Sun with unprecedented resolution in space and time
    At the present time ground-based observatories have a wide range of instruments which can study the solar surface in the visible and infrared ranges. But it is not possible to combine these observations with those in the near ultraviolet, which cover the wavelength range from 200 to 400 nanometres, nor to maintain them for long periods due to the turbulence in the Earth’s atmosphere. In this context, the Sunrise III mission, in which the Instituto de Astrofísica de Canarias (IAC) is collaborating, “ has become the first observatory to obtain spectropolarimetric data simultaneously in the

    Researchers from the IAC discover that dark matter experiences forces beyond gravity
    The existence of dark matter is probably one of the fundamental mysteries of modern science and unraveling its nature has become one of the primary goals of modern Physics. Despite representing 85% of all matter in the Universe, we do not know what it is. In its simplest description, it is made up of particles that interact with each other and with ordinary matter only through gravity. However, this description does not correspond to any physical model. Finding out what dark matter is requires finding evidence of some kind of interaction of dark matter that goes beyond gravity. In our work

    The role of active galactic nucleus feedback on the evolution of dwarf galaxies from cosmological simulations: Supermassive black holes suppress star formation in low-mass galaxies
    Recent observational studies suggest that feedback from active galactic nuclei (AGNs)—the energetic centres powered by supermassive black holes—may play an important role in the formation and evolution of dwarf galaxies, contrary to the standard thought. We investigated this using two sets of 12 cosmological magnetohydrodynamic simulations of the formation of dwarf galaxies: one set using a version of the AURIGA galaxy formation physics model including AGN feedback and a parallel set with AGN feedback turned off. Our results reveal that AGNs can suppress the star formation (SF) of dwarf
