https://doi.org/10.1007/978-3-642-59264-5ich 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 in

These considerations will then lead to a world model, the model of our cosmos. .This chapter will deal with aspects of homogeneous cosmology. As we will see, the Universe can, to first approximation, be con

Von der “Arriflex” zum “Fly-away”is is thermal radiation since the emitting plasma in stellar atmospheres is basically in thermodynamical equilibrium. To a first approximation, the spectral properties of a star can be described by a Planck spectrum whose temperature depends on the stellar mass and the evolutionary state of the star

In the course of this discussion, we will describe a number of methods, each of which is in itself useful for estimating cosmological parameters, and we will
