Dynamical Tidal Locking Theory: A new source of the Spin of Dark Matter Halos

We revisit the question of what mechanism is responsible for the spins of halos of dark matter. The answer to this question is of high importance for modeling galaxy intrinsic alignment, which can potentially contaminate current and future lensing data. In particular, we show that when the dark matt...
