Description
Through gravitational interactions, binary systems can boost the energy of transiting dark matter (DM) particles. I will show how this effect is most efficient for double black hole binaries, which can eject DM with velocities substantially above its typical halo speed. The resulting boosted DM flux from a galactic population of these systems can extend the sensitivity of large-volume detectors, such as PandaX-4T or LZ, to sub-GeV masses in a nearly model-independent manner. Because this mechanism is also largely mass-independent, it can improve sensitivity to inelastic DM, even in the heavy-mass regime.
