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.

    The Interstellar Medium in High-redshift Submillimeter Galaxies as Probed by Infrared Spectroscopy*
    Submillimeter galaxies (SMGs) at z≳ 1 are luminous in the far-infrared, and have star formation rates, SFR, of hundreds to thousands of solar masses per year...

    The interstellar medium of quiescent galaxies and its evolution with time
    We characterise the basic far-IR properties and the gas mass fraction of massive (⟨log(M */M ⊙)⟩ ≈ 11.0) quiescent galaxies (QGs) and explore how these evolve...

    The intracluster light as a tracer of the total matter density distribution: a view from simulations
    By using deep observations of clusters of galaxies, it has been recently found that the projected stellar mass density closely follows the projected total (dark...
