Goal

Study how Galactic Dark Matter conditions affect direct detection and signal modulation

Investigated processes

• Possible non-standard halo models:

  • “Messy” VDFs from simulation

    • G. Lawrence in prep (+ MJZ and GL already working on related project)

  • Gaia sausage (two gaussian distributions)

    • https://arxiv.org/abs/1909.04684

    • https://arxiv.org/abs/1807.02519

  • S1 stream (counter-rotating/retrograde stream)

    • https://arxiv.org/abs/1909.04684

  • Nyx (co-rotating/prograde stream)

    • https://arxiv.org/abs/1907.07681

  • Hemli stream (stream from merger event)

    • https://arxiv.org/abs/1907.07681

  • Koppelman 1 and 2 (also called group 1 and 2, pair of streams from recent accretion)

    • https://arxiv.org/abs/1907.07681

• EFTs with strong dependence on velocity or that allow for strong limits from NaI
