The article discusses a research on bosonic field, alternative form of dark matter with de Broglie wavelength of astronomical scale by Hsi-Yu Schive and othters in the periodical as of June 2014. The topics discussed include use of N-body simulations to study the formation of cosmological structures, and weakly interacting massive particles (WIMPS). Also discussed are attempts to solve Schrödinger equation for the alternative dark matter density.
