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.

These notes are of introductory nature and suitable for graduate students and postdocs wanting to learn the basics of astroparticle physics and cosmology, with a focus on the question of the nature and detection methods of particle dark matter.

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.

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.

The discovery of dark energy has generated enormous interest beyond cosmology and has dramatic implications for fundamental physics. Distance measurements using supernova explosions are the most direct probes of the expansion history of the Universe.
