Sextans' cold substructures as a dynamical judge: Core, Cusp or MOND?
V. Lora, E. K. Grebel, F. J. Sanchez-Salcedo +1
The cold dark matter model predicts cuspy dark matter halos. However, it has been found that, in some low-mass galaxies, cored dark halos provide a better description of their inte…
Dark Matter Subhalos in the Ursa Minor Dwarf Galaxy
V. Lora, A. Just, F. J. Sanchez-Salcedo +1
Through numerical simulations, we study the dissolution timescale of the Ursa Minor cold stellar clump, due to the combination of phase-mixing and gravitational encounters with com…
The survival of dynamical fossils in dwarf spheroidal galaxies in conventional and modified dynamics
F. J. Sanchez-Salcedo, V. Lora
The survival of unbound density substructure against orbital mixing imposes strong constraints on the slope of the underlying gravitational potential and provides a new test on mod…
An upper limit on the mass of the black hole in Ursa Minor dwarf galaxy
V. Lora, F. J. Sanchez-Salcedo, A. Raga +1
The well-established correlations between the mass of massive black holes (BHs) in the nuclei of most studied galaxies and various global properties of their hosting galaxy lend su…
