Animation showing the formation of an ultra-dense galaxy: the giant host galaxy disrupts the smaller galaxy, removing its fluffy outer parts, and the dense center is left behind. The animation then zooms in to a possible embedded planet and supermassive black hole. Modeled using Blender 2.73a and by utilizing Python 3.4

Tidal Stripping
This movies shows a small dark matter halo (1e9 solar masses) that orbits in the vicinity of a larger halo (1e12 solar masses, similar to the Milky Way). Due to the tidal forces, the small halo looses mass over time -- creating stellar streams ahead an behind of the structure.
At the end of the video the small object has only 10% of its initial mass left. This is a quite moderate case of tidal stripping.

Recorded as part of the Cosmic Signals of Dark Matter Physics: New Synergies (#darkmatter-c24) conference at the Kavli Institute for Theoretical Physics (KITP) on Jun 3, 2024 - Jun 6, 2024 in Santa Barbara, CA.
Observables spanning a wide range of cosmic epochs and length-scales independently testify to the existence of dark matter. Although little is known about the microphysical nature of dark matter, its mere existence points to physics beyond the Standard Model. New developments in theory, cosmological simulations, and observational capabilities in the era of large surveys have opened up a vast landscape for dark matter discovery, which includes models that can only be tested by astrophysical and cosmological probes.

2. Synthesize ongoing theoretical, computational, and observational efforts to extract dark matter physics from cosmic observables
3. Identify new synergies between particle and cosmology theorists, simulators, and astronomers working toward constraining the elusive nature of dark matter.
