Abstract :

One alternative to the cold dark matter (CDM) paradigm is the scalar field dark matter (SFDM) model, which assumes dark matter is a spin-0 ultra-light scalar field with a typical mass m�10^{�22}eV/c2 and positive self-interactions. Due to the ultra-light boson mass, the SFDM could form Bose�Einstein condensates in the very early universe, which are interpreted as the dark matter haloes. Although cosmologically the model behaves as CDM, they differ at small scales: SFDM naturally predicts fewer satellite haloes, cores in dwarf galaxies and the formation of massive galaxies at high redshifts. In this talk, we describe this model and show that the SFDM model is an interesting alternative to be the dark matter of the universe.
