DARK ENERGY
Theory and Observations
Dark energy, the mysterious cause of the accelerating expansion of the Universe, is
one of the most important fields of research in astrophysics and cosmology today.
Introducing the theoretical ideas, observational methods and results, this textbook
is ideally suited to graduate courses on dark energy, and will also supplement
advanced cosmology courses.
Providing a thorough introduction to this exciting field, the textbook covers
the cosmological constant, quintessence, k-essence, perfect fluid models, extra-
dimensional models, and modified gravity. Observational research is reviewed,
from the Cosmic Microwave Background to baryon acoustic oscillations, weak
lensing, and cluster abundances. Every chapter ends with problems, with full solu-
tions provided, and any calculations are worked through step-by-step.
luca amendola is Professor of Physics at the University of Heidelberg,
