Dark Matter: In cosmology, dark matter has matter particles that cannot be spotted by their releases of radiation but when they are there, they can be taken from gravitational effects on visible matter such as stars and galaxies.
Black Holes: A black hole is a part of space that has so much mass concentrated in it that if you went near it; there is no chance that you can escape its gravitational pull.
MACHO, and WIMPS: MACHO, and the WIMPS are made up from the particles of dark matter.
CNOC Project: TheCanadian Network for Observational Cosmology It is an international consortium of astronomers who have carried out two major imaging/spectroscopic surveys of distant galaxies using the 3.6m Canada-France-Hawaii Telescope .
Low Z Galaxy Clusters: Galaxies are preferentially found in groups or larger agglomerations called clusters. Low Z Galaxies are lower in mass.
"Wide-Angle" Spectrograph: A type of telescope used at the Canada-France-Hawaii observatory.
