Traces of Galaxy Formation: Stellar populations, Dynamics and Morphology


    Welcome to the Traces of Galaxy Formation research group website.

    We are a large, diverse, and very active research group aiming to provide a comprehensive picture for the formation of galaxies in the Universe. Rooted in detailed stellar population analysis, we are constantly exploring and developing new tools and ideas to understand how galaxies came to be what we now observe.

    A complex star formation history, as the one expected to describe galaxy evolution, needs a multidisciplinary approach to be fully understood. Our group at the IAC consists of experienced researchers in cosmological simulations, dynamical studies, stellar populations and morphological properties of galaxies up to high redshift. We combine different approaches (e.g. observations and theory, secular and cosmological evolution studies) to obtain a complete view of the dominant mechanisms driving the evolution of galaxies.

    Within this general framework, we are currently exploring three main areas of research:

    1. Stellar population synthesis models
      • Development of new stellar population synthesis models
      • Stellar population analysis tools
      • Universality of the stellar initial mass function (IMF)
    2. Cosmic evolution of galaxies
      • Massive galaxy evolution
      • Stellar populations in different environments
      • Low surface brightness science
      • Machine learning and cosmological simulations
    3. Evolutionary processes in nearby galaxies
      • The role of black holes in the evolution of galaxies
      • Surveys of nearby galaxies
      • Stellar kinematics and dynamical models

    • Constraining the formation of inner bars: photometry, kinematics and stellar populations in NGC 357

      Double-barred galaxies are common in the local Universe, with approximately one-third of barred spirals hosting a smaller, inner bar. Nested bars have been proposed as a mechanism to transport gas to the very central regions of the galaxy, trigger star formation and contribute to the growth of the bulge. To test this idea, we perform for the first

      The final product of galaxy evolution through cosmic time is the population of galaxies in the local universe. These galaxies are also those that can be studied in most detail, thus providing a stringent benchmark for our understanding of galaxy evolution. Through the huge success of spectroscopic single-fiber, statistical surveys of the Local

      Context. Observations have shown that inner discs and rings (IDs and IRs) are not preferably found in barred galaxies, which indicates that their formation may differ from that described by the traditional bar-origin scenario in many cases. In contrast, the role of minor mergers in producing these inner components (ICs), while often invoked, is
