General
Description

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

If you want to get in contact or work with us, please send an email to the head of the group (Ignacio Martín-Navarro ignacio.martin [at] iac.es (ignacio[dot]martin[at]iac[dot]es)).

    The study of binary stars is essential to stellar astrophysics. A large number of stars form and evolve within binary systems. Therefore, their study is fundamental to understand stellar and galactic evolution. Particularly relevant is that binary systems are still the best source of precise stellar mass and radius measurements. Research lines
