Observational Probes of Cosmic Acceleration

The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by some form of 'dark energy' with exotic physical properties, or that Einstein's theory of gravity breaks down on cosmological scales. We review in detail the four most well established methods for making such measurements.

The author reviews the current state of determinations of the Hubble constant, which gives the length scale of the Universe by relating the velocity of objects to their distance. Many object-based measurements give H0 values of around 72-74km/s/Mpc.

Gravitational-wave experiments with interferometers and with resonant masses can search for stochastic backgrounds of gravitational waves of cosmological origin. We review both experimental and theoretical aspects of the search for these backgrounds.

This is the summary of lectures given at the Canary islands winter school of Astrophysics: The Cosmic Microwave Background, from Quantum Fluctuations to the present Universe. Lectures were intended for master / beginning PhD students in cosmology.

Dwarf galaxies provide opportunities for drawing inferences about the processes in the early universe by observing our Local Group and its vicinity. This issue is a snapshot of the current state of the art of dwarf-galaxy cosmology.
