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…

A theoretical model for tellurite-sulfates NaCu(TeO)(SO)(OH) and KCu(TeO)(SO)(OH)

I. L. Bartolom/'e, L. Errico, V. Fernandez +3

A theoretical model for two new tellurite-sulfates, namely NaCu(TeO)(SO)(OH) and KCu(TeO)(SO) (OH) is determined to be compatible wi…

Tunable mode entanglement: topological Su-Schrieffer-Heeger (SSH) chain with an embedded Aharonov-Bohm quantum ring

A. P. Garrido, A. R. Plastino, M. L. Ladrón de Guevara +1

We investigate a variant of the SSH model consisting of an SSH chain with an embedded Aharonov-Bohm quantum ring. The embedded ring gives rise to domain wall states whose energy le…
