The scalar field dark matter (SFDM) model proposes that galaxies form bycondensation of a scalar field (SF) very early in the universe formingBose-Einstein Condensates (BEC) drops, i.e., in this model haloes of galaxiesare gigantic drops of SF. Here big structures form like in the LCDM model, byhierarchy, thus all the predictions of the LCDM model at big scales arereproduced by SFDM. This model predicts that all galaxies must be very similarand exist for bigger redshifts than in the LCDM model. In this work we showthat BEC dark matter haloes fit high-resolution rotation curves of a sample ofthirteen low surface brightness galaxies. We compare our fits to those obtainedusing a Navarro-Frenk-White and Pseudo-Isothermal (PI) profiles and found abetter agreement with the SFDM and PI profiles. The mean value of thelogarithmic inner density slopes is -0.27 +/- 0.18. As a second result we finda natural way to define the core radius with the advantage of beingmodel-independent. Using this new definition in the BEC density profile we findthat the recent observation of the constant dark matter central surface densitycan be reproduced. We conclude that in light of the difficulties that thestandard model is currently facing the SFDM model can be a worthy alternativeto keep exploring further.
