SYMPOSIUM 2: Environment and the Formation of Galaxies: 30 years later

It has been thirty years since the seminal work of Alan Dressler on the density-morphology relation, which established environment as a driving mechanism for galaxy formation and evolution. In the following three decades, we have learned that both local processes (nature) and environment (nurture) contribute towards shaping the galaxy populations, and the connection between these two aspects still remains an open question. Large, homogeneous redshift surveys have enabled us to quantify environment in a more consistent way. In addition, large galaxy surveys at different wavelengths allow us to study the physics behind the environmental dependence of galaxy properties. A combination of photo-spectroscopic data along with cosmological simulations of galaxy formation are essential to probe the dichotomy between the mass assembly and the star formation history, in connection with the environment where galaxies live.

Recent and upcoming surveys extend out to the high redshift Universe, where the effect of environment on galaxy formation will be more apparent on the underlying stellar populations. This Mini Symposium brings observations and theory together with the purpose of establishing the role of environment in the star formation and assembly histories of galaxies, including the dependence that look-back time imposes on environment mechanisms. The meeting will include a round table session where the latest results and ideas will be discussed by a number of experts, also encouraging active participation from the audience.
