Cosmological inflation generates primordial density perturbations on all scales, including those far too small to contribute to the cosmic microwave background. At these scales, isolated ultracompact minihalos of dark matter can form, well before standard structure formation, if the small-scale perturbations have a large enough amplitude. Such minihalos affect pulsar timing observations and are potentially bright sources of gamma rays. The resulting constraints significantly extend the observable window of inflation and dark matter, simultaneously probing two of the greatest puzzles in modern cosmology.
