Two other examples of spiral galaxies are shown in Figs. 1.1 and 1.2, one of which we are viewing from above (face-on), the other from the side (edge-on). These are all stellar systems in which the majority of stars are confined to a relatively thin

Excess Volatility und Informationseffizienz,instead we will turn our attention to the space and time in which these objects are embedded. These considerations will then lead to a world model, the model of our cosmos. We need such a model also to interpret the observations of distant objects, i.e., those with a redshift for which the local Hub

As a matter of fact, for several decades cosmologists have considered the determination of the density parameter and the expansion rate of the Universe as their prim

Die formale Beschreibung der Modelle,ich we are able to study astrophysical processes in detail. Therefore, our journey through extragalactic astronomy will begin in our home Galaxy, with which we first need to become familiar before we are ready to take off into the depths of the Universe. Knowing the properties of the Milky Way is indispensable for understanding other galaxies.
