Description |
In this talk, I will explain how the cosmic microwave background is sensitive to the presence of neutrinos and dark radiation, and how minor changes, e.g., an interaction via a new gauge field, can "hide" these particles. I will show that, quite remarkably, this also ameliorates long-standing problems in structure-formation at galactic scales. |
