Grup de Cosmologia Computacional
Welcome!
The Computational Cosmology Group (GCC) is an ongoing cosmological research project group, which began in 2004 at the Department of Astronomy and Astrophysics at the University of Valencia, Spain.
Our research focuses on unraveling the complex physical processes that govern the formation and evolution of cosmic structures, from the astrophysics that shapes galaxies to the cosmology that reigns over the cosmic web. Through state-of-the-art large-scale hydro(magnetic)dynamical simulations and advanced computational techniques, we seek to bridge the gap between theoretical predictions and observational data.
Objectives and purposes
We aim to illuminate the fundamental mechanisms driving cosmic evolution: understanding how primordial density fluctuations grow into the rich tapestry of structures we observe today, how galaxies form and evolve within their dark matter halos in different environments, and how feedback processes from stars and supermassive black holes shape the properties of galaxies and galaxy clusters.
Computational Approach
Our simulations employ a cutting-edge numerical code named MASCLET that incorporates comprehensive physical models, including gravity, hydrodynamics, radiative cooling, star formation, stellar and AGN feedback, and magnetic fields. These simulations run on Lluis Vives (UV) supercomputing facilities, allowing us to model cosmic volumes with high resolution. Further details of our simulations can be found in the Simulations section.
We develop and maintain several major simulation projects spanning different cosmic scales and physical features, enabling us to investigate a wide range of astrophysical and cosmological phenomena.
Collaboration
The GCC is part of a vibrant international network of cosmologists and astrophysicists. We actively collaborate with observational groups and contribute to the interpretation of data from major facilities including space missions and ground-based telescopes. Our work helps guide observational strategies and provides theoretical context for understanding the Universe's structure and evolution.
