Constraining the shape of dark matter haloes using only starlight II. Tests of the technique with objects of known gravitational potential

Jorge Sanchez Almeida, Angel R. Plastino, Sergio Guerra Arencibia +2

Under the collisionless cold dark matter (CDM) paradigm, galaxies with stellar masses below 10**(5-6) Msun are expected to preserve primordial cuspy dark matter (DM) profiles. Beca…

The slow evolution of dark matter halos from cusp to core naturally produces extended stellar core-like distributions

Jorge Sanchez Almeida, Angel R. Plastino, Ignacio Trujillo

Motivated by the observation of extended stellar cores in dark matter (DM) dominated dwarf galaxies, this study investigates a simple mechanism by which stellar cores can form as a…

The stellar distribution in ultra-faint dwarf galaxies suggests deviations from the collision-less cold dark matter paradigm

Jorge Sanchez Almeida, Ignacio Trujillo, Angel R. Plastino

Unraveling the nature of dark matter (DM) stands as a primary objective in modern physics. Here we present evidence suggesting deviations from the collisionless Cold DM (CDM) parad…

Application of the Eddington inversion method to constrain the dark matter halo of galaxies using only observed surface brightness profiles

Jorge Sanchez Almeida, Angel R. Plastino, Ignacio Trujillo

*** Context: The halos of low-mass galaxies may allow us to constrain the nature of dark matter (DM), but the kinematic measurements to diagnose the required properties are technic…
