Descriptions
Acbar: Arcminute Cosmology Bolometer Array Receiver
Radio interferometry experiment of the CMBR
BAO: Baryonic Acoustic Oscillations
In the early universe the density fluctuations of dark matter generate a gravitational potential, in which the baryonic
matter performs acoustic oscillations. These oscillations depend on the density parameters of the universe.
CBI: Cosmic Background Imager
Radio interferometry experiment of the CMB
CMB: Cosmic Microwave Background
CMBR: Cosmic Microwave Background Radiation
ISW: Integrated Sachs Wolfe effect
A temperature shift in the CMB caused by a time variation of the potentials ˙Ψ, ˙Φ.
LRG Luminous Red Galaxies
Special distant objects observed by SDSS.
OSW: Ordinary Sachs Wolfe effect
A temperature shift in the CMB caused by climbing out of the gravitational potentialΨ,Φ.
SN1a: Type 1a Supernovae
A white dwarf, which exceeds its mass-limit and starts a nuclear carbon fusion. The luminosity of these stars is
well known and can be used for obtaining the luminosity distance.
SDSS: Sloan Digital Sky Survey
SDSS is a redshift survey which aims to observe 100 million objects on the sky.
SUSY: SUperSYmmetry
A symmetry used in particle physics, to unify the three fundamental interactions electro-magnetisms and the weak
and strong force by introducing super partners to every particle.
WMAP: Wilkinson Microwave Anisotropy Probe
A satellite, which measured the CMBR-Anisotropies. In particular the first peak in the CMB-C l-Power spectrum is
measured by WMAP.
