Fundamental properties of the dark and the luminous matter from Low Surface Brightness discs

Dark matter (DM) is one of the biggest mystery in the Universe. After a brief discussion of the past DM evidences and the main proposed candidates and scenarios for the DM phenomenon, I will focus on rotating disc galaxies giving a special attention to the Low Surface Brightness (LSB) galaxies. The main observational properties related to the baryonic matter in LSBs, analysed over the last decades, will be briefly recalled. Next, I will show the main results that I obtained by means of the mass modelling of the LSBs rotation curves (URC analysis). Finally, the results will be compared to those of different kinds of galaxies and contextualised in the large DM phenomenon
