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…
Dynamical friction of massive objects in galactic centres
A. Just, F. M. Khan, P. Berczik +2
Dynamical friction leads to an orbital decay of massive objects like young compact star clusters or Massive Black Holes in central regions of galaxies. The dynamical friction force…
