dc.description.abstractThe aim of this work is to model the observed velocity of our galaxy relative to the cosmic microwave background that was recently discovered by Smoot et al. A homogenous and isotropic,flat, relativistic two fluid cosmological model is considered in which two separate fluids act as the source of the gravitational field. In this model one fluid is a comoving radiative perfect fluid modelling the cosmic microwave background and the second a non-comoving imperfect fluid modelling the observed material content of the universe. The model that is obtained is represented as a solution of Einstein's equations and the laws of thermodynamics in which all the physical quantities occurring in the solution are suitably well behaved. In addition, the model is in good agreement with current observations.en_US
dc.description.abstractLe but de ce travail est de modeler la vitesse observée de notre galaxie par rapport aux microondes cosmiques de fond découvertes récemment par Smoot et al. On considère un modèle cosmologique qui est homogène, isotropique, plat et relativistique composé de deux fluides distincts qui sont la source du champ gravitationnel. Dans ce modèle, un des fluides est un fluide parfait, radiatif et codéplacent qui représente les microondes cosmiques de fond et I'autre fluide représente Ie contenu matériel observé de I'univers. Le modèle ainsi obtenu est représenté sous forme d'une solution aux équations d'Einslein et les lois de la thermodynamique dans laquelle toutes les quantités physiques qui s'y trouvent se comportent normalement. En plus, Ie modèle s'accorde bien avec les observations actuelles.
