DOI: 10.1007/s10509-020-03858-7

Abstract: We use the Iocco et al. (2015) compilation of 2,780 circular velocity measurements to analyze the Milky Way rotation curve. We find that the error bars for individual measurements are non-gaussian, and hence instead derive… read more here.

DOI: 10.1016/j.dark.2018.07.002

Abstract: We have recently introduced a new model for the distribution of dark matter (DM) in galaxies based on a self-gravitating system of massive fermions at finite temperatures, the Ruffini-Arguelles-Rueda (RAR) model. We show that this… read more here.

DOI: 10.1051/0004-6361/201527346

Abstract: In this work, two new axisymmetric models for the Galactic mass distribution are presented. Motivated by recent results, these two models include the contribution of a stellar thin disc and of a thick disc, as… read more here.
