FRAMEWORK FOR COSMOGRAPHY AT HIGH REDSHIFT
Abstract We propose a geometrical framework which is adapted for the investigation of Large Scales Structures at high redshifts in curved spaces, within the Standard world model of Universe. It is based on the embedding of the comoving space onto the 4D metric space, which provides us with a useful algebra-representation of objects positions in space. In particular, the interpretation and the calculation of geometrical quantities, such as distances between objects, angles, surfaces and volumes, become obvious. Moreover, elements of cartography provides us with global view of the Universe which accounts for the curvature. A quasars catalog is used for having a visual support. This framework is implemented in a free-share routine called {\em Universe Viewer} which is accessible at {\bf cpt.univ-mrs.fr/cosmology/UV}.
Initial project started by R. TRIAY, S. SPINELLI, R. LAFAYE October 1995 CPT-94/P.3138
Project restarted in 2003 by R. TRIAY, V. LECOQ, X. LAUGIER Java Version released in 2008 by M. ABATI, J. FONTAINE
I still want to modernize this project and add new features like as correction of light distortion due to gravity
