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
The paper validates a photometry‑based Eddington Inversion Method (EIM‑tool) that tests whether observed stellar distributions are physically consistent with cuspy or cored dark‑ma…
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…
Constraining the shape of dark matter haloes using only starlight. I. A new technique and its application to the galaxy Nube
Jorge Sanchez Almeida, Ignacio Trujillo, Mireia Montes +1
We present a new technique to constrain the gravitational potential of a galaxy from the observed stellar mass surface density alone under a number of assumptions. It uses the clas…
