In my thesis, several methods of extracting some of the most important cosmological parameters such as density and bias are developed. All these methods rely on the analysis of the large-scale motions of galaxies. If galactic motions are affected mainly by gravity, then the study of large-scale flow should in principle be able to probe the underlying mass distribution and thus the density parameter. Comparison of this inferred mass distribution with the observed distribution of galaxies is however complicated by the lack of understanding of the relationship between mass and light. Nevertheless if a simple bias correlation between mass and light is assumed, then such study would be a very useful tool for testing some of the cosmological theories. The thesis starts off with a brief introduction to some of the basic cosmological principles that are relevant to my work. It then continues with the details of the analysis mentioned above using chiefly the data from the IRAS (Infrared Astronomical Satellite) survey along with the results. The thesis then ends with an overview of the current state of the large-scale motion study in the field of cosmology.
