  1. 13. Migdal effect: New insights and updated predictions
    Dr Christopher McCabe (King's College London)
    22/09/2022, 15:30

    Previous calculations of the Migdal effect assumed small values of the nuclear recoil velocity and were limited to the ionisation of single electrons. I will discuss new calculations of the Migdal effect that are robust for any conceivable value of the nuclear recoil velocity and allow for the ionisation of multiple electrons. Our results enable robust predictions of the Migdal effect...

  3. 15. Maximising sensitivity to low mass dark matter with the Migdal effect and exploring non-standard models including isospin violation in liquid noble direct detection experiments

    Liquid noble direct dark matter detection experiments aim to detect galactic dark matter scattering off nuclei in highly sensitive detectors in underground laboratories. As positive signals of dark matter in the lab are elusive, it is crucial that current and future experiments broaden the reach and scope of dark matter models which are explored. In this presentation I will report on work...

  4. 16. Constraining Dark Matter Spikes with OJ287
    Prof. Malcolm Fairbairn (Physics, King's College London)
    22/09/2022, 16:30

    We use the extreme black hole binary system OJ287 to place constraints on dark matter spikes expected outside supermassive black holes as predicted by theory.

  5. 17. Signatures of Non-thermal Dark Matter with Kination and Early Matter Domination: Gravitational Waves versus Laboratory Searches
    Dr Lucien Heurtier (IPPP, Durham, England)
    22/09/2022, 16:50

    The non-thermal production of dark matter (DM) usually requires very tiny couplings of the dark sector with the visible sector and therefore is notoriously challenging to hunt in laboratory experiments. Here we propose a novel pathway to test such a production in the context of a non-standard cosmological history, using both gravitational wave (GW) and laboratory searches. We investigate the...
