The Hubble Constant
by Neal Jackson
Publisher: arXiv 2014
Number of pages: 48
The author reviews the current state of determinations of the Hubble constant, which gives the length scale of the Universe by relating the expansion velocity of objects to their distance. Many, but not all, 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 text introduces some basic problems arising in gravitation and modern cosmology. All along the discussion the guiding theme is provided by the phenomenological and theoretical properties of the Cosmic Microwave Background (CMB).

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.

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.
