Cosmological and extragalactic astrophysical research deal with transformational and evolutionary processes on vast scales of space and time. Observations can only provide snapshots of these evolutions, confined in redshift due to limited telescope power.     

        In the era of high-performance computing and big data analysis, numerical simulations of astrophysical and cosmological processes represent well-suited means to overcome the problem of large scales in space and time and to tackle the question of the actual physics behind cosmological and astrophysical evolutionary processes. Numerical simulations hence drive the transformation of cosmology and extragalactic astronomy from descriptive towards analytic science. 

        In the recent years, spectacular progress has been made in simulating the cosmological emergence of the large-scale structure of the Universe. Large international projects, such as the famous MILLENNIUM simulation, have established nothing less than a new view of what the Universe looks like. But also simulations on smaller scales have been remarkably successful, providing new insights into the formation and evolution of galaxies with respect to their environment. As both computational and telescope power will increase, the field of computational astrophysics and cosmology will grow further and – in interaction with improving observational data – contribute significantly to the development of our understanding of the Universe. 

        This workshop aims at introducing students and young researchers to the methods of astrophysical simulations and – with a strong emphasis on hands-on learning – at making them able to participate in the promising future developments of this exciting field of research.
