Lines of research: Formation & Evolution of Galaxies (FYEG)

Formation & Evolution of Galaxies (FYEG)

Galaxies are formed progressively through a complex combination of gas accretion, star formation and merger processes with other galaxies. The aim of the Galaxy Formation & Evolution research line is to unveil the physical mechanisms responsible for the most significant transformations in these objects. The research team that makes up the research line is strongly involved in the development of forefront instrumentation (EMIR, FRIDA, GTCAO, HARMONI, OSIRIS, WEAVE) and has an important role in the scientific exploitation and  development of international projects (SDSS, EUCLID, LSST) for the study of the formation and evolution of galaxies.

 
The line stands out for studies on the three-dimensional structure of the Milky Way (including its system of globular clusters and satellite galaxies), the characterisation of stellar populations and dynamics of nearby galaxies, the cycle of activity of supermassive black holes at the centres of  galaxies, the conditions of the interstellar medium in the first galaxies, and the role of dark matter in their evolution. Besides, thanks to the recently created simulations group, we also aim to relate observations with theory by means of numerical models over cosmological volumes and thus obtain predictions for future observations.

    Explaining the chemical trajectories of accreted and in-situ halo stars of the Milky Way
    The Milky Way underwent its last significant merger ten billion years ago, when the Gaia-Enceladus-Sausage (GES) was accreted. Accreted GES stars and progenitor...

    Explaining the Galactic Interstellar Dust Grain Size Distribution Function
    We present here a new theoretical model designed to explain the interstellar dust grain size distribution function (IDGSDF), and compare its results with...

    Exploring the making of a galactic wind in the starbursting dwarf irregular galaxy IC 10 with LOFAR
    Low-mass galaxies are subject to strong galactic outflows, in which cosmic rays may play an important role; they can be best traced with low-frequency radio...

    Exploring the Mid-infrared SEDs of Six AGN Dusty Torus Models. I. Synthetic Spectra
    At distances from the active galaxy nucleus where the ambient temperature falls below ̃1500-1800 K, dust is able to survive. It is thus possible to have a large...
