Figure with two panels, the left one shows the ratio of the mass enclosed within r_2D and 4.5 r_2D as a function of r_2D for the gravothermal evolution of a self-interacting dark matter halo with elastic scattering. The right panel shows the same but for dissipative interactions.
llustration of the evolution and the mechanisms acting on an isolated self-interacting dark matter halo, which becomes bound to a host system over time.
Illustration of the interaction between two numerical particles to model dark matter scattering.
Plot of the density as a function of radius for a simulation of a dark matter satellite halo. The density profile is shown at several times together with observed densities from ultra-faint dwarfs.
Plot of the projected logarithmic density slope as a function of the projected enclosed mass, shown for five different radii. The isothermal jeans model and an N-body simulation are compared with each other.
View of a building at the Donostia International Physics Centre. The logo with the letters DIPC can be seen on the façade.
