Tunneling and tidal stripping in multifield ultralight dark matter halos
Benjamin V. Lehmann, Jackie Lodman, Thomas Steingasser
Tidal stripping is a key feature of the evolution of dark matter (DM) halos, and has major implications for the population of low-mass galaxies. In the case of ultralight DM, tidal…

Fast and Fewrious: Stochastic binary perturbations from fast compact objects
Badal Bhalla, Benjamin V. Lehmann, Kuver Sinha +1
Massive compact objects soften binaries. This process has been used for decades to constrain the population of such objects, particularly as a component of dark matter (DM). The ef…

Dancing with invisible partners: Three-body exchanges with primordial black holes
Badal Bhalla, Benjamin V. Lehmann, Kuver Sinha +1
The abundance of massive primordial black holes has historically been constrained by dynamical probes. Since these objects can participate in hard few-body scattering processes, th…
