Oscillations of dark matter halos in galaxies and their effects on motion of stars

I. B. Samsonov, V. V. Flambaum

Offsets between centers of mass of dark matter and ordinary matter in galaxies drive relative oscillations that alter stellar velocities.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Such oscillations, if exist, should manifest themselves in anomalies of velocities of stars in the galaxy, such as the density waves and runaway stars which have orbit periods in resonance with oscillations.

C2weakest assumption

Ignoring internal dynamics of particles in the dark matter halo and Keplerian rotations of matter in the galaxy while assuming the offset of the centers of mass is small as compared with the size of the galaxy.

C3one line summary

Dark matter halos may oscillate relative to galactic matter after collisions, producing resonant effects on star motions such as density waves and runaway stars.
