New Insights into the Universe

Indispensable for the building of cosmological models are precise observational data. To provide such data is the main purpose of this book. First, an analysis of recent cosmological observations using artificial satellites and large ground-based telescopes is given. Among these are the observation of the spatial distribution of galaxies and clusters, the detection of peculiar velocity fields in large regions, and the measurement of anisotropies in the microwave background radiation. Second, the authors present theoretical models which best fit the given observational data. The book addresses graduate students and astronomers and astrophysicists.

Autorentext
The lectures of this summer school address astrophysicists and especially graduate students. The authors present observational data gathered by artificial satellites and ground-based telescopes. The findings are compared with theoretical cosmological models.

Klappentext

Indispensable for the building of cosmological models are
precise observational data. To provide such data is the main
purpose of this book. First, an analysis of recent
cosmological observations using artificial satellites and
large ground-based telescopes is given. Among these are the
observation of the spatial distribution of galaxies and
clusters, the detection of peculiar velocity fields in large
regions, and the measurement of anisotropies in the
microwave background radiation. Second, the authors present
theoretical models which best fit the given observational
data. The book addresses graduate students and astronomers
and astrophysicists.
