EPP Theory Seminar: Harikrishnan Ramani: Pulsar timing probes of Dark matter clumps


Millisecond pulsars are known to be very stable clocks, whose fluctuations in the periods of pulses observed over decades do not accumulate. We use the stability of these astrophysical clocks to derive prospects for a signature of transiting dark matter substructure from frequency dependent fluctuations in the pulsar period. We apply our results to single and multiple transiting primordial black holes as well as the CDM paradigm.
