The diverse density profiles of galaxy clusters with self-interacting
  dark matter plus baryons
  We present the first simulated galaxy clusters (M_200 > 10^14 Msun) with both
self-interacting dark matter (SIDM) and baryonic physics. They exhibit a
greater diversity in both dark matter and stellar density profiles than their
counterparts in simulations with collisionless dark matter (CDM), which is
generated by the complex interplay between dark matter self-interactions and
baryonic physics. Despite variations in formation history, we demonstrate that
analytical Jeans modelling predicts the SIDM density profiles remarkably well,
and the diverse properties of the haloes can be understood in terms of their
different final baryon distributions.
