Diversity of the Local Universe

The nearby Universe is a key tool for understanding structure formation and galaxy evolution. It allows us to study the distribution in space and bulk motion of matter with unsurpassed accuracy. Here, we can observe the inner structure of nearby objects in great details. We may study the physical processes in individual star-forming regions and analyze stellar populations using individual stars. Due to relatively small distances, we observe a huge number of dwarf galaxies in the nearby Universe; a census which is simply impossible for regions further away. Dwarf galaxies play an important role in galaxy evolution throughout cosmic time. These “simple” low-mass objects provide us a detailed view on stellar, chemical, and dynamical properties in the Universe. The aim of this conference is to bring together the broad community studying the Local Universe and the place of dwarf galaxies within it.
