【 摘 要 】

We discuss some possible astrophysical and cosmological connections between dark matter and sterile neutrinos. Both the controversies at small scales for traditional cold dark matter (CDM) and anomalies in neutrino experiments seem to suggest that there might be new self-interactions for dark matter and sterile neutrinos. Surprisingly, if the new interaction also mediates between dark matter and sterile neutrinos, "missing satellite problem" in CDM paradigm can also be solved. On the other hand, light sterile neutrinos with self-interacting can also satisfy the cosmological bounds.
