No significant deviations from the Standard Model predictions have been observed at particle physics experiments, except for neutrino masses. On the other hand, astrophysical evidence for dark matter also points to new physics. In theories beyond the Standard Model of particle physics, neutrino masses and dark matter might have a common origin. Additionally, these theoretical models predict...
Gravitational dynamical friction is expected to cause the orbits of globular clusters to shrink as a function of time. This effect may offer a unique probe of the particle dark matter paradigm. We discuss this effect, and compare the dark matter prediction to observational data of globular cluster-rich, dark matter-dominated dwarf galaxies.
