The Hubble ConstantThe Hubble Constant
by Neal Jackson - arXiv , 2014
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.
Observational Probes of Cosmic AccelerationObservational Probes of Cosmic Acceleration
by David H. Weinberg, et al. - arXiv , 2012
The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by dark energy. We review in detail the most well established methods for making such measurements.
Multi-messenger Astronomy and Dark MatterMulti-messenger Astronomy and Dark Matter
by Las Bergstrom - arXiv , 2012
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.

Supernova Cosmology: Legacy and FutureSupernova Cosmology: Legacy and Future
by Ariel Goobar, Bruno Leibundgut - arXiv , 2011
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.
Gravitational Wave Experiments and Early Universe CosmologyGravitational Wave Experiments and Early Universe Cosmology
by Michele Maggiore - arXiv , 2000
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.
Dwarf-Galaxy CosmologyDwarf-Galaxy Cosmology
by Regina Schulte-Ladbeck, at al. - Hindawi Publishing , 2010
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.
Why CMB physics?Why CMB physics?
by Massimo Giovannini - arXiv , 2007
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).
