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…

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…

Can cuspy dark matter dominated halos hold cored stellar mass distributions?

Jorge Sanchez Almeida, Angel R. Plastino, Ignacio Trujillo

According to the current concordance cosmological model, the dark matter (DM) particles are collision-less and produce self-gravitating structures with a central cusp which, genera…

Physically motivated fit to mass surface density profiles observed in galaxies

J. Sanchez Almeida, I. Trujillo, A. R. Plastino

Polytropes have gained renewed interest because they account for several seemingly-disconnected observational properties of galaxies. Here we study if polytropes are also able to e…

The principle of maximum entropy explains the cores observed in the mass distribution of dwarf galaxies

Jorge Sanchez Almeida, Ignacio Trujillo, Angel Ricardo Plastino

Cold Dark Matter (CDM) simulations predict a central cusp in the mass distribution of galaxies. This prediction is in stark contrast with observations of dwarf galaxies which show…
